Customer Reviews (4.6 / 5 · 5 reviews)

Kevin E. ★★★★★

The black oxide finish is holding up nicely on my jigs after a few weeks of constant handling, no rust spotting at all. I’ve used about 200 of these in precision assemblies and not one stripped head, even with the small 2.5mm hex drive. For 600 pieces at this grade, the value is hard to beat.

Olivia V. ★★★★★

These have a nice tight thread engagement that makes a big difference in small jig work. The black oxide finish feels durable and professional, exactly what I needed for precision tooling.

Ruby ★★★★★

Used a full bag of these on a custom jig build and every single one threaded smoothly into 2.5mm tapped holes without any binding. The black oxide coating seems durable and hasn't flaked off during installation.
