Customer Reviews (4.8 / 5 · 5 reviews)

Madison ★★★★★

Installing these on a press tool and the partially threaded design made alignment much easier than fully threaded bolts. The black oxide finish looks clean and professional against the steel.

Benjamin L. ★★★★★

I needed some strong hardware for a jig I'm building, and these partially threaded screws grabbed tight in the steel plate without stripping. The hex socket drive made installation easy even in a tight spot.

Ava ★★★★★

The black oxide finish on these screws held up perfectly during my jig assembly, no chipping or scratching like cheaper ones I've used. That partial threading made installation into a tapped hole much smoother than expected.
