Customer Reviews (4.8 / 5 · 5 reviews)

Avery M. ★★★★★

Used these on a small jig I was building, and the fully threaded design made it easy to dial in the exact depth. The brass finish gives them a nice look against steel parts too.

Nicholas D. ★★★★★

The brass finish on these screws looks great against the aluminum parts I'm using them on. They threaded cleanly into my jig without any binding, and the 1/4" length is perfect for securing thin panels.

Leo B. ★★★★★

The hex socket drive fit my wrench perfectly for a tiny jig repair—these brass screws are solid. Threads were clean and seated without any binding. Exactly what I needed for precision work in tight spaces.
