Olivia S. ★★★★★

The black oxide finish came out of the package uniform and slick, no rough edges on the threads at all. I've torqued a handful of these into steel tooling plates and the 10.9 alloy holds up without stripping the hex drive, even at 40Nm.

Mia ★★★★★

Installed a set of these on a jig I'm building and the black oxide finish held up perfectly against my wrench marks. The hex socket drive engaged firmly without any stripping. Exactly what I needed for a tight assembly.

Chloe ★★★★★

The threads are cut perfectly clean and the black oxide finish gives them a nice, even look that hasn't chipped during install. Used these on a jig build and the hex socket drive seated every single one without stripping, even at 100mm length.
