Steven U. ★★★★★

I’ve been using these M18 bolts to secure some heavy machinery mounts, and the class 8.8 steel has held up perfectly under load. The zinc plating gives them a nice clean look too, no rust forming after a few weeks in a damp shop.

John ★★★★★

Finally, a fully threaded M18 that doesn’t strip out when I torque it down. The hex head grips the socket cleanly, and the zinc coating is holding up fine after a week of machine assembly.

Adam I. ★★★★★

The 50mm length is perfect for the heavy-duty machinery mounts I needed to secure. The hex heads are sharp and clean, so my socket wrench grabbed them without slipping. These fully threaded M18 bolts feel solidly made for the price.
