Threaded the full 280mm into a heavy press frame, and the 10.9 steel held rock solid under full load. The hex head gave a clean grip with a socket wrench, no stripping at all. Exactly what I needed for high-torque assembly work.

These bolts handled the torque on my excavator’s track adjustment without a hitch, and the 10.9 grade steel feels rock solid. The partially threaded shaft worked perfectly for the deep flange I was bolting. Exactly what I needed.

I needed a heavy-duty bolt for a press frame repair, and the 280mm length was exactly what I needed to get a solid bite through the flanges. The hex head fits my socket perfectly, and the thread engagement on the nut feels tight and true.
