Customer Reviews (4.4 / 5 · 5 reviews)

Zoe N. ★★★★★

The partially threaded section made cinching this bolt down in a tight access point much easier than a fully threaded one would have been. These M30s feel solid and the hex head grabbed perfectly with a standard socket.

Timothy I. ★★★★★

These bolts threaded in smoothly on our assembly jig and held firm under heavy load without any stripping. The hex heads gave a solid grip for the impact wrench, making installation quick. Exactly the right length for our large machinery build.

Joshua ★★★★★

Exactly what we needed for the press frame repair—the class 8.8 steel feels properly tough, and the partially threaded shaft gave just the right grip length. The hex head grabbed the wrench cleanly, no stripping on the drive. Three in the pack was a good spare to have on hand.
