Customer Reviews (4.4 / 5 · 5 reviews)

Abigail ★★★★★

Needed a heavy-duty bolt for a press jig I'm rebuilding, and these black oxide screws handled the torque beautifully without slipping. The nylon patch held firm during final assembly, saving me from adding thread locker.

Steven E. ★★★★★

Installed these on a jig that sees daily use, and the black oxide finish still looks good after a few weeks of tightening and loosening. The hex drive engaged snugly with my wrench, no stripping issues.

Matthew ★★★★★

The nylon patch works perfectly—holds tight under vibration but still lets me turn them with a hex key. Used these on a jig for a heavy machining job and they held up without any issues.
