Customer Reviews (4.6 / 5 · 5 reviews)

Alexander ★★★★★

Finally tracked down the right size for a custom tooling fixture I’ve been working on—the nylon pellet really locks the threads in place. These black oxide screws hold tight without any galling during assembly.

Ella ★★★★★

I used a few of these on a jig I’m building and the 5/8-18 threads cut smoothly into the steel. The nylon pellet does a nice job keeping them from backing out under vibration, which I was worried about.

Miles ★★★★★

The nylon pellet locking them in place is a lifesaver on my tooling fixture—no more chasing loose screws after a few cycles. The black oxide finish gives them a clean look and they’ve held up fine so far without any galling. Exactly what I needed for a precision assembly.
