Customer Reviews (4.6 / 5 · 5 reviews)

Charlotte X. ★★★★★

These replaced some worn bolts on a metalworking clamp and the 8.8 steel grade holds up perfectly to the torque. The hex head made them easy to drive with a socket and the partial thread let me snug them down evenly.

Victoria ★★★★★

Used these on a small jig fixture for workholding and the hex heads held torque perfectly without stripping. The 40mm length and partial threads made alignment easy on thicker brackets. Solid grip with a standard socket wrench.

Stella O. ★★★★★

The partially threaded design is exactly what I needed for clamping two brackets without the threads chewing up the gap. Wrenching them in with a 8mm socket felt solid, and the zinc coating looks clean and uniform across all 400 pieces.
