Customer Reviews (4.6 / 5 · 5 reviews)

Evelyn ★★★★★

I had to replace some corroded fasteners on a saltwater dock, and these 316 stainless screws are holding up perfectly with zero rust so far. The fully threaded design made it easy to get full engagement in the thick wood.

Chloe ★★★★★

Box of 300 came in handy for a big assembly job I had going. The 316 stainless feels solid and the fully threaded length made alignment easier than I expected, though the hex head could use slightly sharper edges.

Michael R. ★★★★★

The hex head grabs a socket wrench perfectly, so I got all 300 threaded into place without a single stripped one. 316 stainless means I'm not worrying about rust on these outdoor fittings.
