Customer Reviews (4.6 / 5 · 5 reviews)

Ava ★★★★★

These are seriously beefy bolts. I needed them for attaching a heavy bracket to a steel beam, and the 316 stainless gives me peace of mind about corrosion in a damp environment.

Sebastian A. ★★★★★

I’ve been using these 316 stainless screws to replace rusted hardware on a saltwater dock, and after three weeks they still look perfect. The coarse 1-1/4-7 threads bit into the steel effortlessly without stripping. Off to buy another pack for the next repair.

Ryan ★★★★★

These 316 stainless hex cap screws threaded cleanly into my marine hatch assembly without any binding. The fully threaded design gave me plenty of grip for a solid, lasting hold.
