Customer Reviews (4.4 / 5 · 5 reviews)

Richard ★★★★★

The nylon pellet in these is a nice touch—it locks the threads in place without needing a drop of Loctite. I’ve used a handful on a drill fixture and they’ve held firm through a full day of vibration.

Isabella V. ★★★★★

The nylon pellet on these is a lifesaver—they hold position under vibration way better than plain threads. The black oxide finish also looks sharp on my tooling fixtures, and the hex drive seated cleanly without stripping.

Julian ★★★★★

I needed some quality screws for a jig I'm building and these fit the bill perfectly. The hex socket drive makes installation a breeze, and the black oxide coating adds a nice touch of corrosion resistance.
