Customer Reviews (5.0 / 5 · 5 reviews)

Miles ★★★★★

Used these to mount a heavy bracket to a steel beam, and the 3-1/2 inch length gave me just enough thread engagement without being too long. Flat head sat flush with the surface perfectly. So far no rust even after a week of rain.

Evelyn ★★★★★

I needed some high-torque stainless fasteners for a boat railing repair, and these 18/8 screws felt substantial and seated perfectly in the pre-tapped holes. The flat heads sat flush without any burrs, which saved me a ton of sanding time—definitely what I needed.

Alexander ★★★★★

The Phillips head on these machine screws bit perfectly without any cam-out, which made installing them in a tight spot much less frustrating. They feel solid and the stainless steel finish looks clean against the wood.
