Why 316 Marine Grade Stainless Steel Screws Are the Gold Standard for Coastal Builds

From seaside decks to high-moisture builds, 316 stainless steel screws are the gold standard when you need maximum durability and zero rust. Designed for saltwater exposure and harsh outdoor conditions, these marine-grade screws combine the strength of stainless steel with the added corrosion-fighting power of molybdenum, making them ideal for jetties, docks, boardwalks, fencing, and high-end exterior woodworking.

At Eagle Claw Fasteners, we’ve fine-tuned our 316 screws alongside professional carpenters to ensure optimal performance. Each screw features a Torx drive to prevent cam-out and preserve your tools, while the polished finish keeps your timber looking clean and free of ugly rust stains. Compatible with hardwoods, softwoods, and pressure-treated timber, these screws grip tight, go in smoothly, and stay exactly where they should.

If you're building in a coastal zone, wet climate, or simply want the best, 316 stainless steel deck screws deliver the strength and reliability your project deserves, without compromise. No shortcuts, no stains, no do-overs. Just fasteners that finish strong.

Freqently Asked Questions

What are 316 marine grade stainless steel screws used for?

316 marine grade stainless steel screws are ideal for outdoor, coastal, and saltwater-exposed projects like decks, docks, boardwalks, and fencing. Their superior corrosion resistance makes them the go-to choice for marine construction and high-humidity environments.

Will 316 stainless steel screws rust in saltwater?

No. 316 stainless steel contains molybdenum, which gives it outstanding resistance to rust, pitting, and corrosion, even in direct saltwater contact or marine spray zones.

Are 316 stainless steel deck screws better than 304 for outdoor use?

Yes. While both offer corrosion resistance, 316 stainless steel deck screws are better suited for harsh environments like coastal regions or wet applications due to their higher molybdenum content.
