Steven M. ★★★★★

I needed some extra length for a stubborn adjustment, and these 3-inch screws gave me the reach to finally get it right. The hex socket drive held steady under some serious torque without stripping.

Aurora ★★★★★

The cup point bites into the shaft like it’s supposed to, and even after cranking them down with a hex key, the threads on all 100 feel clean and uniform. Took a full afternoon to use most of a box on a jig and didn’t strip a single one.

Mia H. ★★★★★

I was worried that with the hex socket drive these would be tricky to tighten, but the high-torque adjustment made setting them super easy even in a cramped mounting bracket. The cup point tip digs in nicely to hold firm without slipping.
