Customer Reviews (4.8 / 5 · 5 reviews)

Kevin ★★★★★

Installed these on a marine railing and the 316 stainless handles the salt air perfectly. The hex socket drive made tightening them in tight corners much easier than I expected.

Adam ★★★★★

I needed corrosion-resistant fasteners for a marine jig, and these 316 stainless screws fit the bill perfectly. The hex socket drive made installation a breeze, and the partially threaded section gripped tight.

Leo N. ★★★★★

The partially threaded design made alignment in my jig setup way easier than I expected, and the 316 stainless finish looks clean against the tooling. These 3-inchers are solid and haven't shown a hint of corrosion after a few weeks in a damp shop.
