Customer Reviews (4.8 / 5 · 5 reviews)

Eva Z. ★★★★★

Used these on a custom jig I've been building and the hex socket drive made tightening them in tight spots way easier than a regular bolt. The fully threaded length gives a solid grip when I need to adjust clamping pressure on the fly. Exactly what I needed for precision work.

Jason V. ★★★★★

The hex socket drive gripped perfectly without stripping, which was a relief during assembly. These 316 stainless steel screws feel solid and corrosion-resistant for my outdoor jig project.

Ryan ★★★★★

Installed these in a marine deck railing repair, and the 316 stainless is already proving corrosion-resistant after a week of salt spray. The fully threaded body gave me plenty of grip length for the spacer I needed.
