Amelia R. ★★★★★

Installed these on a heavy press and the B7 alloy handled the torque without any issue. The partially threaded design made alignment much easier than fully threaded bolts I've used before.

Sebastian N. ★★★★★

The threads on these 1"-8 x 9" B7s cut clean and the partial threading gives you that extra grip where you need it. I've got them holding a jig frame and they torqued down without any galling, which I appreciate. Solid buy for heavy equipment work.

Kevin ★★★★★

Installing these on a large press assembly, the threads cut clean and the hex head gave my wrench solid bite without slipping. The 9-inch length was exactly what we needed for this heavy load-bearing connection.
