Customer Reviews (4.8 / 5 · 5 reviews)

Abigail ★★★★★

I was happy to find these in 316 stainless since my last batch rusted near saltwater. The hex drive seated perfectly in my small jig without stripping.

Kevin ★★★★★

Exactly the right size for my jig setup, and the 316 stainless finish feels solid out of the bag. Four hundred is a lot of screws, but for the price I’m glad I’ve got extras for future builds.

Christopher ★★★★★

Perfectly uniform threads on every single screw — no burrs or sticky spots at all. The hex socket drive makes them way easier to tighten in tight spaces compared to Phillips heads. Exactly what I needed for a jig project.
