Charlotte E. ★★★★★

Inch-perfect fit on these—I used them to bolt down a jig on my mill and the 40mm length was exactly what I needed. The hex socket drive bit down clean without any stripping, and the black oxide coating seems like it'll shrug off the shop oil.

Victoria S. ★★★★★

The black oxide finish on these M12s is the real deal—no chips or scratches after installing them into my jig setup, and the 40mm length seats perfectly with a standard hex key. Fifty in a box means I’m set for a while, which is exactly what I wanted for a batch of tooling projects.

Lily ★★★★★

I needed some heavy-duty screws for a new tooling setup, and these M12-1.75 x 40mm cap screws drove in smoothly without stripping. The black oxide finish feels tough and looks clean against the steel.
