Ellie Q. ★★★★★

Needed a handful for a custom jig I’m building, and these fit perfectly—the hex drive seated cleanly without any stripping. The black oxide finish is a nice bonus for a bit of corrosion resistance, feels solid.

John ★★★★★

The hex socket on these M12 screws is precisely machined—my Allen wrench fits snugly with zero wobble. I use them for jig fixtures, and the 12.9 grade is noticeably tougher than the 8.8 stuff I was buying before.

Jason ★★★★★

These arrived with a clean, even black oxide finish and the hex sockets were cut perfectly, no rounded edges. I used them to bolt down a drilling jig and they seated flush without any binding. For the price per hundred, these are a solid buy for any precision assembly work.
