The black oxide finish on these screws gives them a nice uniform look, and the hex drive seated perfectly with my tooling setup. They tightened evenly into the jig without any binding. Exactly the quality I was hoping for in a batch of fasteners.

I needed a batch of solid M10 cap screws for a machinery repair, and the black oxide finish on these gives just enough corrosion protection for my shop floor. No stripped heads after torquing them down, which is exactly what I was hoping for.

Machined a few fixture plates this weekend and the socket heads seated perfectly with a hex key, no stripping or wobble. The black oxide coating looks uniform and should hold up fine in the shop. These are exactly what I needed for precision assemblies.
