براغي رأس سداسي ثقيلة 7/8-9 × 9-1/2\" | فولاذ سبائكي ASTM A193 B7 عادي | خيط جزئي (22 / عبوة)

Threads cut cleanly and the hex heads grabbed my socket with no rounding. These B7 bolts feel tough enough for the heavy press rebuild I’ve got them in.

The partially threaded length is perfect for my flange connections—gives solid grip without bottoming out in the blind hole. The B7 alloy has held up fine under repeated torque checks so far.

I've been using these bolts on a heavy press fixture and the 9-1/2" length gives plenty of thread engagement without bottoming out. The alloy steel feels noticeably stiffer than the standard grade 5 stuff I used before, so I'm confident they'll hold up under repeated torque.
