Customer Reviews (4.4 / 5 · 5 reviews)

Benjamin ★★★★★

Needed some heavy-duty fasteners for a jig I was building, and the 75mm length paired with that 12.9 alloy steel rating gave me confidence they wouldn't snap under load. The black oxide finish also seems like it'll resist shop grime better than plain steel.

Avery A. ★★★★★

The hex socket drive bit into my torque wrench without any wobble, and the 75mm length with partial threading seated perfectly in my jig setup. All 100 pieces came out of the box with a consistent, even black oxide coating—no burrs or rough edges to clean up.

Miles ★★★★★

The black oxide finish gives these a nice, uniform look that resists smudging during assembly. I popped a few into a steel jig today and the hex socket drive seated cleanly with no stripping—the 12.9 alloy steel feels properly rigid.
