Steven M. ★★★★★

The partially threaded design makes seating these in blind holes way easier than I expected, and the 316 stainless finish is flawless across all 300 pieces. I've already used two dozen on a jig build and the hex drive hasn't stripped once.

Hazel ★★★★★

The hex socket drive is a perfect fit for my jigs and fixtures, and the 316 stainless steel gives me confidence they won't corrode. Used a dozen to secure a new machine guard, and the partially threaded design held tight.

Joshua ★★★★★

Finally found some M4 hardware that doesn't strip out—the hex socket drive grabs perfectly with my Allen key. The 316 stainless feels solid, and I love that they're partially threaded for clamping down jigs.
