Customer Reviews (4.8 / 5 · 5 reviews)

Claire M. ★★★★★

The hex head gave my socket wrench a solid grip, and the 8.8 steel held up fine when I torqued them down on the machine frame. Glad these partially threaded screws didn't strip out like cheaper ones usually do.

Harper P. ★★★★★

Used these for mounting some conveyor brackets and the partial thread makes alignment much easier than a fully threaded bolt. The 55mm length was just right for our setup.

Benjamin ★★★★★

Needed a batch of these for a small production run and the class 8.8 steel holds up well under torque. The hex heads fit a standard socket perfectly, saving time during assembly.
