Customer Reviews (4.8 / 5 · 5 reviews)

Leo O. ★★★★★

I was replacing some worn bolts on a milling jig and these M12-1.25 x 100mm screws fit perfectly. The thermal black oxide finish is smooth and even, and the partial threading gave me just the right grip depth for the fixture.

Eli ★★★★★

The 25-pack arrived well-organized, and the 100mm length with partial threading made them perfect for a jig I’m building. The hex socket drive seated cleanly in my driver without any wobble, and the black oxide finish feels tough already.

Ella F. ★★★★★

Black oxide finish on these M12 screws looks great and seems to resist corrosion better than the plain steel ones I've used before. The hex socket drive makes installation straightforward even in tight spots on my jig.
