Steven M. ★★★★★

The threads engage cleanly and the hex socket drives true without stripping, even when I torqued them down on a jig fixture. For a full box of 400 zinc-plated alloy steel screws at this price, they're a solid deal.

Emma ★★★★★

I was honestly surprised how well the zinc plating held up after drilling several pilot holes—no chipping at all. The 40mm length is perfect for my precision assemblies, and the hex socket drive fits snugly.

Ella ★★★★★

Been using these for jigs and fixtures on the shop floor for a couple weeks now, and the zinc plating is holding up way better than the last batch I bought. The hex socket drive seats cleanly with no stripping, and the partial threading makes them solid for clamping.
