Customer Reviews (4.4 / 5 · 5 reviews)

Isabella T. ★★★★★

I've been using these to repair a jig at work, and the partially threaded design made alignment much easier than fully threaded screws. The hex drive holds tight without stripping, even under repeated torque.

Ryan ★★★★★

I’ve been using these in a custom jig I’m building and they’ve held up great under repeated tightening. The hex socket drive makes it easy to get good torque, and the thermal black oxide finish hasn’t shown any wear so far.

Zoe P. ★★★★☆

The black oxide finish on these screws resists rust well in my shop, and the hex drive makes them easy to install with a standard Allen key. They held up fine in my jig setup without stripping. Only wish they came in a slightly longer length.
