Nicholas K. ★★★★★

The partially threaded section made alignment a breeze when I was bolting down a heavy base plate, and the hex head gave my socket a solid grip without slipping off. Finish is plain as advertised, but for the price these are exactly what a machine shop needs on hand.

Julian ★★★★★

The threads on these M30 bolts engaged perfectly with the nut on my assembly jig, no wobble at all. The 280mm length gave me just enough clearance for a thick steel plate. Solid Class 8.8 steel that really holds torque.

Eva P. ★★★★★

Installed these on a heavy press that kept loosening standard bolts. The M30 thread bites deep and the 8.8 steel feels solid enough for the job. Tightened with a socket and they haven't budged yet.
