Michael N. ★★★★★

Torqued a few of these into a steel jig plate today and the black oxide finish held up without any galling. The Class 10.9 alloy steel feels reassuringly solid for the price, and all 400 pieces looked uniformly threaded right out of the box.

Thomas M. ★★★★★

The hex socket drive on these screws made installation so much easier with my jig setup—no cam-out issues at all. The thermal black oxide finish looks great on the tooling I built.

William ★★★★★

Used a whole box of these on a custom tooling fixture and every single one threaded in clean without a single stripped head. The black oxide finish has a nice even coating that held up well to handling with oily gloves. At 400 per pack, they're a solid buy for anyone doing production work or jigs.
