Customer Reviews (4.8 / 5 · 5 reviews)

Emily H. ★★★★★

I needed low-profile M12 bolts for a tight jig assembly, and these 20mm ones fit perfectly into the recessed pocket with no interference. The black oxide coating seems consistent and hasn't flaked during installation.

Christopher ★★★★★

The hex socket drive seated perfectly on my wrench with zero stripping, and the 12.9-grade alloy feels solid for the jig I'm building. These fully threaded M12s bit into the metal cleanly without any binding.

Sebastian I. ★★★★★

Needed a dozen for a fixture on the mill table and the thread engagement on these is surprisingly clean, no burrs. The black oxide finish held up fine against cutting fluid during the job.
