Hannah M. ★★★★★

Put these on a press frame that needed sturdy bolts. The threading ran clean all the way, and the 320mm length was spot on for the thick flanges we were joining. Exactly what class 8.8 should feel like.

Emma D. ★★★★★

The hex head on these caught the wrench perfectly, no slipping even when I torqued them down on the equipment frame. Partially threaded design made alignment a lot easier than fully threaded ones I've used before. Solid Class 8.8 steel, these aren't going anywhere.

Lucy ★★★★★

The threads on these M24-3 bolts are cut clean and the hex heads fit a socket perfectly, no rounding off even with a breaker bar. I used a full pack on a heavy press frame and every one seated flush without any burrs. Solid buy for the price.
