Customer Reviews (4.8 / 5 · 5 reviews)

Steven N. ★★★★★

This one goes right in the tool drawer with the rest of my jig hardware. The black oxide finish looks properly done and should resist rust well in the shop, and the nylon patch means I don't need to reach for thread locker on a precision assembly.

Ruby ★★★★★

I used a few of these to fasten a heavy bracket to a steel machine frame, and the 5-1/2" length gave me just enough bite through thick sections. The hex socket drive held up well under torque without stripping.

Avery ★★★★★

The black oxide finish on these screws matched the existing hardware on my tooling cart perfectly, and the nylon patch held strong during assembly without needing separate thread locker.
