Customer Reviews (4.8 / 5 · 5 reviews)

Joshua E. ★★★★★

Needed these for a jig fixture at work, and the black oxide finish on these screws feels really durable. The nylon patch held tight during a test fit, no loosening at all.

Alexander ★★★★★

I picked up a pack for building a heavy-duty jig and the black oxide finish looks great against the steel. The hex socket drive made installation straightforward, and the partial threading let me secure everything firmly.

Adam ★★★★★

Right on spec for my jig build—the black oxide finish has a nice, even matte look and the hex socket seated my Allen key without any slop. Threads cut smoothly into the tapped holes, and the nylon patch held firm during a quick test run. These are going to last.
