براغي ذات رأس سداسي ثقيلة 7/8-9 × 6-1/2 بوصة | ASTM A193 B7 فولاد سبيكي عادي | خيط جزئي (30/عبوة)

The partially threaded length is exactly what I needed for bolting through a thick flange, and the 7/8-9 threads bit cleanly without chasing. Held torque perfectly on a pump skid I reassembled, and the 30-count box means I’ve got spares for the next job.

The threading was clean and the partially threaded length grabbed perfectly for my equipment mount. Pack of 30 is solid value for B7 alloy at this size.

I needed heavy-duty fasteners for a pump base repair, and these B7 screws handled the torque without any issue. The partial threading made alignment easier than fully threaded bolts I've used before.
