Customer Reviews (4.8 / 5 · 5 reviews)

Emma A. ★★★★★

Got these for a small robotics project, and the black oxide finish on the alloy steel looks really clean and hasn't shown any rust yet. The hex socket drive made them easy to torque down precisely without stripping.

Amelia I. ★★★★★

Used a full pack on a custom jig for my shop and every single one threaded clean with zero stripped heads. The thermal black oxide seems tough too, no chips after a week of heavy clamping.

Harper ★★★★★

The black oxide finish on these screws gives them a nice, professional look for jigs and fixtures. They seated perfectly in my drill jig without any binding or stripping.
