Customer Reviews (4.8 / 5 · 5 reviews)

Violet ★★★★★

I was pleasantly surprised by how well the black oxide finish holds up; after installing a few in a jig they show no wear at all. The 12.9 alloy steel feels noticeably tougher than the stainless I've used before.

Sebastian ★★★★★

The hex socket drive engages perfectly with my driver—no stripping, even at higher torque. These 12.9 alloy screws feel exceptionally hard and durable for precision tooling. Exactly what I needed for small-scale machinery fixturing.

Joseph M. ★★★★★

Used a handful of these in a small CNC fixture and the black oxide finish held up great against coolant spray. They thread in smooth and the hex drive grabs perfectly with a 2mm bit—no stripping at all. Exactly the right spec for precision work.
