Customer Reviews (4.4 / 5 · 5 reviews)

Scarlett R. ★★★★★

I've been using these as replacement axles for some jig fixtures in my workshop, and the fit is exactly what I needed. The socket head makes installation with a hex key really straightforward, without stripping out.

Carter ★★★★★

The precision-ground shoulder on these screws made a noticeable difference in how smoothly my axle assembly rotates. I’ve already used a few as pivot points on a custom jig and they fit perfectly without any wobble.

Penelope X. ★★★★★

The precision-ground shoulder on these is exactly what I needed for a smooth pivot on a jig I was building—no slop whatsoever. They came out of the package clean and the hex socket drive bit down without stripping. Just the right fit for the job.
