براغي رأس سداسي ثقيلة 7/8-9 × 7-1/2" | ASTM A193 B7 سبيكة فولاذ عادي | خيط جزئي (27 / عبوة)

Finally got around to replacing some flange bolts on a press that kept vibrating loose, these B7s are a perfect fit and the partial threading made alignment easier. The 27-count package gives you a few spares for the next job too.

Needed these for a pump coupling repair and the partially threaded shank gave just the right grip depth without bottoming out. Fit the tapped holes perfectly and the alloy steel feels substantial.

The hex heads on these bolts are deep and grab the socket firmly with no slipping, and the threaded portion is just right for bolting down a heavy bracket. Worked perfectly for securing a motor mount on an industrial press.
