Eagle Claw vs DeckMate Screws: Which Is Better for Fences and Outdoor Wood?

Deck Mate is cheap, it's at every Home Depot, and it drives in clean, which is why people grab a few boxes for a fence without thinking twice. But underneath that tan or black coating it is carbon steel, and a fence lives outdoors for decades.

The real question for those pickets is whether a coating or solid stainless steel deck screws hold up when the screws sit in wet, copper-treated wood and tannin-heavy cedar.

We carry both kinds and have pulled a lot of rusted, stained screws out of old fences, so we put Eagle Claw vs Deck Mate head to head on material, cedar staining, rust, strength, and price. The answer depends on the fence.

What should you use on a fence, Deck Mate or Eagle Claw stainless steel deck screws?

For a fence, use Eagle Claw 304 stainless steel deck screws inland and 316 near salt when the fence is cedar, redwood, or anything you want to keep, and reach for Deck Mate coated when you want a fast, cheap install on a short-term, inland, non-cedar fence.

Both meet code on treated pine. The split comes down to cedar staining and how long you want the screws to outlast install day.

Here's how you decide whether to use Deck Mate or Eagle Claw deck screws:

• If your fence is cedar or redwood, go with stainless steel deck screws. The black tannin staining alone makes a coated screw a mistake, and it's permanent.
• If your fence is near salt air or water, run 316 stainless steel deck screws, full stop.
• If it's a short-term, budget, or non-cedar pine fence you won't keep long, Deck Mate will get you there and it drives fine.
• If you're setting ground-contact posts, that is the most corrosive spot on the fence, so use stainless steel deck screws or a rated structural connector there.
• If you're running stainless steel fence picket screws into a dense or hardwood picket, pre-drill so the softer metal doesn't snap.
• If you're hanging woven or welded wire instead of boards, that's a staple job, not a wood-screw decision.

The rest of this breaks down why, with real numbers and the parts the box leaves off.

What you're actually comparing: coated carbon steel vs stainless steel deck screws

The core difference is where the rust protection lives. A Deck Mate is carbon steel with a coating on the outside; an Eagle Claw screw is stainless steel through its whole cross-section. We dig into that split on its own in our coated vs stainless steel deck screw guide.

How each screw fights rust

• Deck Mate (coated): Carbon steel under a polymer or 4-layer ceramic finish (a zinc layer, an adhesion layer, an epoxy shell, and a colored topcoat). The coating is the whole rust plan, so a scratch through it exposes bare steel.
• Eagle Claw (solid stainless steel deck screws): The chromium is alloyed through the whole screw, so there is no skin to lose, and a scratch reforms a thin protective layer almost instantly instead of exposing anything that rusts.

Think of a coated screw like a painted fence post. It's protected only while the paint is intact. Solid stainless steel deck screws are more like a post made of weatherproof material right through the middle. That self-healing layer is why they can take a beating during installation and still hold up.

One fair point before we go further. Home Depot also sells a "DeckMate" 316 marine stainless steel line that's priced like other SS deck screws.

The cheap coated screw most people mean by "Deck Mate" is the tan or black carbon-steel one, and that's the screw this comparison is about. We're comparing cheap coated against solid stainless steel deck screws, not two stainless steel screws.

One of our customers put it bluntly in a review: "Not a single head twist off and they do not corrode," and said his were still bright years later. That is the spot Eagle Claw sits in.

304 vs 316 stainless steel: what's the difference

The difference between 304 and 316 stainless steel deck screws is one ingredient. Both are austenitic 300-series stainless steel, but 316 adds about 2 to 3% molybdenum that 304 lacks, and that's what makes 316 the marine grade.

Salt is the reason it matters. Chloride from salt air sneaks through the protective layer and starts tiny pits that eat inward, and the molybdenum in 316 blocks that. 304 can begin pitting with surprisingly little salt around, which is why it struggles right at the coast. Inland, in normal weather, 304 stainless steel deck screws do the job and cost less. Both grades are recognized fastener materials under ASTM F593, the stainless steel fastener specification, and our own 304 vs 305 vs 316 guide breaks down which one to buy.

Can you use coated screws on a cedar fence? The black-streak problem

You can, but you usually shouldn't, and this is the single biggest reason to go with stainless steel fence screws. Cedar and redwood are loaded with natural tannins, and when iron from a steel screw meets those tannins plus a little rain, you get a dark blue-black stain that bleeds down from every screw head.

It's a real chemical reaction, not just surface rust. Iron plus tannin makes a compound called iron tannate, the same chemistry people used to make ink hundreds of years ago. It usually shows up the first morning after rain or dew, once moisture lets the iron and the tannins meet.

The USDA Forest Products Laboratory on iron staining in cedar and redwood names cedar, redwood, and oak as the worst offenders and says plainly that stainless steel deck screws are the best fastener choice here.

Can you remove black streaks from a cedar fence?

You can't fully remove black streaks from a cedar fence while the screw is still in the wood. The dark stain is bonded into the wood fibers, not sitting on top, so you can't scrub it off. Oxalic acid wood bleach fades it, but as long as a rusting screw keeps feeding the reaction, it comes back.

As one Reddit user warned someone trying to clean their fence, the bleach works but the stain returns "after another rain or two."

On a privacy fence, a big surface you stained or sealed on purpose, black halos around every screw ruin the whole look. The only real fix is to pull the reactive screws and run stainless steel fence picket screws instead.

Will galvanized screws stain cedar?

Yes, galvanized screws will stain cedar eventually. Galvanized is zinc-coated steel, and once the zinc wears or chips, the iron underneath reacts with cedar's tannins the same way.

Hot-dipped galvanized lasts longer than thin shiny zinc plating, but it still tends to stain over time, and the cedar industry only recommends it under paint or solid stain. The shopper's rule is simple: if the screw is shiny, keep it off cedar.

Will a coated screw stain cedar?

Yes, a coated screw will stain cedar once the coating is breached, and that's the part people miss. A coated screw is fine right up until the coating gets nicked or the threads wear through, and then the bare steel rusts and you're back to blue-black streaks.

A fence builder on Reddit put it well: with ceramic coated screws on cedar "you may get lucky," but it's hit and miss, and the only reliable option is stainless steel wood screws. Even the companies selling coated screws agree. SPAX prints "Not recommended for Cedar or Redwood" right on its coated HCR-X box.

Solid stainless steel deck screws end the problem because they don't leak free iron into the wood, so the reaction never starts. Simpson Strong-Tie's material-selection guide for wood fasteners flags cedar, redwood, and oak as tannin-rich and points to stainless steel for exactly this reason.

We've seen it on our own customers' jobs too. One ran our screws on a cedar picket fence, said they were excellent quality at a much better price than the box stores, and said he'd buy them again. Our full breakdown lives in the best screws for cedar fencing if a cedar fence is your whole project.

Rust, the coating problem, and the code

This is the section the whole decision turns on. A coated screw is only protected while the coating is whole, and a fence is a hard place to keep a coating whole. Simpson Strong-Tie's corrosion guidance for treated-wood fasteners lays out why fastener material matters so much in treated wood and salt air.

How driving the screw wears the coating off

A coating gets breached in the two spots a fence screw can least afford:

• The cut threads. A self-starting tip is built to cut through wood, so the coating at the thread edges takes the most abrasion. The hardest-working parts lose their protection first and end up buried deepest in the wet wood.
• The head and shank. Friction shaves the coating as the screw drives in, so the protection is often compromised before the fence is even finished, right where moisture loves to sit.

A builder on Reddit explained it perfectly: the coatings "work well in a lab," but they get scratched off during driving, and after pulling boards at only two or three years he found a lot of the screws rusted or snapped. Another noted that coated screws "should really be used only once," because the coating mostly stays behind in the wood the first time.

Do Deck Mate screws rust?

Yes, Deck Mate screws rust once the coating is breached, which usually happens while you drive them. They resist rust while the coating is whole, but underneath they're carbon steel, not stainless steel, so the protection is a barrier rather than something built into the metal.

Modern pressure-treated lumber makes it worse on purpose. The research shows three things:

• It works like a weak battery. The wood is infused with copper (usually ACQ or copper azole), and that copper drives a slow electrical reaction with the steel in the screw.
• The wood feeds on the screw. The reaction pulls metal off the screw and corrodes it from the inside, even with no rain at all. Researchers buried fasteners in damp treated wood with zero weather exposure and still measured corrosion.
• Today's lumber is harder on metal than the old stuff. Studies put modern treatments at roughly two to five times more corrosive than the older CCA lumber, which is why a screw that lasted on a 1990s deck can fail much sooner now.

You can read the federal data in USDA Forest Products Laboratory research on fastener corrosion in treated wood.

How long do Deck Mate screws last?

Deck Mate screws last roughly 10 years in mild, dry, inland conditions if the coating stays intact. In treated lumber that drops to about 7 to 10 years, and in salt or coastal air it can be as little as 2 to 5 years. Solid stainless steel deck screws, by contrast, typically outlast the wood they're holding, so on a fence you only fasten it once.

The field reports back up the low end. One homeowner in inland Florida, nowhere near the water, said his started breaking "at about the third year" and had rusted right through. A Reddit contractor compared a 50-year-old galvanized nail in good shape against a "rusted out 5 year old Deckmate screw" on the same deck.

About those salt-spray numbers on the box, the 500-hour and 1,500-hour claims. That's a lab test (ASTM B117) for comparing one coating to another, not how many hours the screw survives on your fence. The lab that wrote the standard says it doesn't reliably predict real-world life. Don't read "1,500 hours" as a calendar.

When Deck Mate is fine, when Eagle Claw stainless steel deck screws are the call

Both screws are good. The choice is about matching the screw to the fence, so here is where each one fits.

Deck Mate coated is the right call when:

• The wood is pine or treated pine, not cedar or redwood, so there's no tannin to react with.
• Looks aren't the priority, so a little staining down the road won't bother you.
• The fence is inland and dry, away from salt air and standing water.
• The connection is non-structural, just pickets and rails, not load-bearing.
• You won't keep the fence long, like a rental, a dog run, a temporary screen, or a property you're selling.

Eagle Claw stainless steel deck screws are the right call when:

• It's a cedar or redwood fence you want to look clean, because the staining alone settles it.
• It's within about 3 miles of the coast, a bay, or a pool, where 316 is the answer.
• It's ground contact at posts and rails, the most corrosive zone on the fence.
• It's a fence you want to outlast you, where buying once saves you redoing it.

A coated screw will give you around 10 years in mild, sheltered conditions, which is plenty if you're not keeping it. We've heard from plenty of folks who ran tan coated screws on inland projects with no trouble, and they're always quick to add the same qualifier: "I don't live by the ocean." That's the dividing line.

The pros who build for a living drift the same direction:

• The signmaker: mounts hardware outdoors, says cheap coated screws "rust fairly quickly," and defaults to stainless steel deck screws.
• The inland builder: with no salt air to blame, watched Deck Mate corrode, then watched a second coated brand corrode too, and concluded you have to use stainless steel wood screws in modern treated wood.
• The South Florida fence contractor: put galvanized screws in a treated picket fence, found them rusting and the pickets rotting around them three years later, told the client he'd done her wrong, and switched to stainless steel fence screws.
• The deck restoration crew on YouTube: put it cleanest, that stainless steel "does not rust in pressure treated lumber and stops the rust-to-rot cycle."

For fence-specific guidance from an outside authority, University of Georgia Extension's guidance on fence fasteners lands in the same place: fence hardware has to be corrosion-resistant or the fence doesn't last.

Things to keep in mind: If you're hanging woven or welded wire, field fence, or hardware cloth, that's a staple job, not a screw decision. Cat's Claw fence staples are the modern upgrade over old U-staples, and they're stainless steel so they won't rust-stain the wood at the contact point. We carry the Cat's Claw fence-staple line. The screw comparison here only applies to the wood members: pickets, rails, and post connections.

The stainless steel deck screws we'd use on a fence that lasts

For a fence we want to build once, we run Eagle Claw 304 grade stainless steel deck screws inland and 316 marine grade stainless steel deck screws within about three miles of salt. The spec, either grade:

• Size: #8 x 1-5/8 inch or #8 x 2 inch for pickets; #10 x 2-1/2 inch or #10 x 3 inch for rails to posts
• Grade: 304 inland, 316 within three miles of salt
• Drive: T20 star on #8, T25 star on #10
• Point: Type 17 self-drilling, no pilot hole in cedar
• Coating: none, it is solid stainless steel through and through

The deep star drive kills cam-out, which is the one thing reviewers consistently praise even on a Deck Mate. These are the screws people mean when they search "eagle claw deck screws review," and the short version is solid 304 or 316 SS deck screws, star drive, no coating, no black stains on cedar down the road.

Who it is for: anyone building a cedar or redwood fence that has to look clean, anyone near salt water, and anyone tired of pulling rusted, sheared screws out of a fence a few winters in.

The proof we trust most is our own customers on real jobs:

• A professional deck builder drove 450 of our screws with a single strip-out, ran short, finished the job with a cheaper brand, and watched the heads shear off several of the cheap ones, so he's coming back to Eagle Claw.
• A customer running 316 on a dock called them "good 316 SS screws for high corrosive areas."
• Another summed his up as "good quality, good value, no surprises."
• On Reddit, one builder called them "the best deck screws for PT decking" and good value, and another said simply that "Eagle Claw makes some great ss screws."

Things to keep in mind: Never put deck field screws, stainless steel or coated, into a load-bearing post or rail connection. Use a rated structural connector and the screws it's listed for. We carry Simpson Strong-Tie stainless steel connectors and structural screws for exactly that spot.
