These M8 black oxide screws fit perfectly into my jig fixtures and the hex drive was clean and stripped-free. Each screw threaded smoothly into the tapped holes without any binding. Exactly what I needed for this batch of tools.

I needed a batch of strong, low-profile bolts for a tooling fixture, and these M8 flat heads have perfect thread engagement without stripping. The black oxide finish also resisted scratching during tightening, which is a nice bonus.

The black oxide finish on these is really uniform, no flaking or bare spots across the whole hundred pack. They drive in cleanly with a hex key and hold tight in my jig setup without stripping.
