Why Choose Our Deck Screws?

Designed in close collaboration with carpenters in the field, these top quality screws are manufactured according to our specifications by our supplier in Taiwan.   

When it comes to constructing a durable and visually appealing deck, the choice of deck screws is crucial. One popular option is 304 grade stainless steel deck screws, known for their strength and corrosion resistance. In this article, we will explore the benefits of stainless steel deck screws, provide step-by-step instructions on installation techniques and address common questions about pre-drilling and countersinking deck screws.

Benefits of 304 Grade Stainless Steel Deck Screws

Superior Corrosion Resistance
304 grade stainless steel deck screws are highly resistant to rust and corrosion, making them ideal for all outdoor applications, especially in wet, coastal, or high pollution environments.

304 grade stainless steel deck screws possess good tensile strength and can effectively fasten deck boards to a timber support structure, providing structural stability.

Aesthetic Appeal
These screws have a sleek and polished appearance that will not rust and stain the wood, enhancing the overall visual appeal of your deck.

304 grade stainless steel deck screws can be used with all types of hard and softwoods, including pressure-treated lumber, cedar, and composite decking materials.


Different Types of Deck Screws:

Most types of decking screws are available in Stainless Steel, or High Carbon Steel with a Galvanized, Coated or Plated anti-rust treatment. Drive types also differ, with Torx (Star), Robertson (Square Drive), Pozi Drive and Phillips among the most popular.

  • Traditional Deck Screws

    These screws have a sharp point and coarse threads approximately two thirds of the length of the screw, with a smooth shank. The head is generally flat countersunk, or bugle countersunk, and these screws are designed for fixing timber to timber.

  • Composite Deck Screws

    Specifically engineered for use in composite decking materials, these screws often feature self-drilling technology and smaller heads. Coatings are often available in a variety of colors to match the plank color selected.

  • Hidden Deck Fasteners

    These innovative screws are not visible on the top of the deck boards, either screwing in through the corner of the plank or utilizing a clip system locating in pre-machined grooves in the sides.

Why Choose Eagle Claw Fasteners?

We are specialists in Stainless Steel Fasteners and have sold millions of screws to many happy customers all over the world since 2012!

Eagle Claw Fasteners are designed and tested in the USA and manufactured at our facility in Taiwan.

All our screws use Torx (Star) Drive technology, which is the best available drive on the market today, allowing maximum driving torque with minimal chance of stripping or camming.

While not self-drilling, our screws have nibs under the head which help the screw seat in the countersunk hole, and a Type- 17 point for ease of driving.

Our six popular sizes cover most woodworking applications in this category and are available in a range of convenient pack sizes.

Choosing the Best Deck Screw for Your Project

Consider the Wood Type and Thickness: Different wood species have varying densities and characteristics, so select deck screws of an appropriate size to ensure a secure and long-lasting connection.

Material Compatibility: If using composite or treated decking, choose screws specifically designed for this material.

Environmental Factors: Assess the climate conditions in your area, including exposure to coastal or damp conditions, and opt for corrosion-resistant screws to maintain durability.

How to Install Deck Screws

Select the Right Tools: Use a drill/driver with an appropriate screwdriver bit (included in all our pack sizes) and a depth stop collar or torque control to ensure consistent screw depth. An impact driver is an invaluable tool, and we recommend using one if possible. A gut-line helps to keep rows of screws in perfect alignment. Use wedges to ensure that gaps between boards are consistent. Always lay a straight board first and work out from that, checking as you go.

Should you pre-drill for deck screws?

Yes! In most cases, pre-drilling clearance holes is recommended to prevent wood splitting, especially on the ends of the planks.


Should you Countersink deck screws?

In hardwoods, this is the correct way to set the screw heads at a consistent depth just below the surface of the plank. We highly recommend our Starborn Combination Bit to countersink the head and drill the clearance hole in one operation.

Installing the Screw: Take care not to overtighten and risk damaging the deck board. Stainless Steel Screws are softer than Carbon Steel screws. Maintain consistent spacing for a professional finish.


What size should the pilot hole for deck screws be?

There are two aspects to consider in the pre-drilling process:  The clearance hole, and the pilot hole. The clearance hole should only be drilled through the decking board, and the diameter is to be slightly larger than the screw's thread diameter. If using a new Pine substructure, generally it is not necessary to drill a pilot hole for the thread into the substructure. However, if laying new decking on old Pine, or if using a hardwood substructure, you will need to drill a pilot hole for the thread. This diameter should be slightly smaller than the thread.

How to Protect and Maintain Deck Screws

Stainless Steel screws need no maintenance as such. They will turn a little greyer than silver after installation, but this is normal.

Keep your deck swept and clean, and don’t allow leaves and debris to accumulate.

Note any screws that may stand proud of the decking surface due to wood shrinkage over time. Drive these in flush as you would when installing.

By choosing stainless, you can ensure a sturdy and visually appealing deck that will stand the test of time.
