براغي رأس سداسي ثقيل 7/8-9 × 3 بوصة | ASTM A193 B7 سبيكة فولاذ عادي | خيط جزئي (55/عبوة)

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.

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.

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.
