Customer Reviews (5.0 / 5 · 5 reviews)

Avery ★★★★★

The hex socket drive made installation quick even in a tight spot on my welding jig. These 316 stainless screws look clean and feel solid, no corrosion worries outdoors.

Joshua ★★★★★

Installed these in a custom fixture where I needed real corrosion resistance, and the 316 stainless is clearly the real deal. The partially threaded shank gave me a solid 2 inches of grip without bottoming out, and the hex socket drive seated perfectly with my allen key. They're pricey for five scre

Benjamin ★★★★★

These hex screws replaced worn ones on a marine jig, and the 316 stainless is holding up perfectly in the salt air. The hex drive seated firmly without stripping.
