Customer Reviews (5.0 / 5 · 5 reviews)

Madison ★★★★★

These partially threaded bolts worked perfectly for securing the base of our large air compressor. The threading is clean and the hex heads gripped my socket without slipping. A solid buy.

Isabella ★★★★★

Needed a solid set of heavy-duty bolts for a press I’m rebuilding, and these 7/8-9 x 3" hex heads fit the bill perfectly. The alloy steel feels plenty tough, and the partial threading made it easy to cinch down without binding.

Chloe ★★★★★

Threads cut smooth and the partial threading is exactly where I wanted it for a frame repair. These B7s aren't budging under torque, and the 55-count box means I've got spares for the next job.
