Customer Reviews (4.6 / 5 · 5 reviews)

Claire L. ★★★★★

The partially threaded section grabbed perfectly when I torqued it down, and the hex head sat flush without any wobble in the wrench. Class 10.9 steel feels reassuringly solid for this kind of heavy machinery work, and it handled the load without complaint on the first run.

Scarlett ★★★★★

Got these to replace a worn-out bolt on a big press at work. The Class 10.9 steel feels seriously tough, and the 340mm length gave me just enough thread engagement without bottoming out. Perfect fit for heavy-duty assembly.

Henry ★★★★★

The partially threaded section grabbed just enough thread to seat the bolt firmly without any wobble, and the 10.9 steel feels like it'll outlast the machine it's holding. For a single M42 of this size, the plain finish is exactly what I needed for a clean, dry fit.
