Leo Q. ★★★★★

Thread engagement is spot-on for jig work, and the flat heads sit flush without any wobble. They’re a bit of a pain to get out once torqued in, but that’s par for the course with black oxide - I’ve already ordered another pack.

Carter ★★★★★

The black oxide finish on these M8 bolts looks fantastic against my machine frame, and the hex socket drive made installation a breeze even in tight spots. A full hundred pieces at this length is perfect for ongoing projects.

Sofia ★★★★★

I needed black oxide for a jig build, and these flat heads seated perfectly flush without any wobble. The 40mm length was spot on for my application with M8 threads.
