براغي ذات رأس سداسي ثقيل 7/8-9 × 3-1/2 بوصة | صناعة أمريكية | فولاذ عادي درجة A307 Grade B | ملولبة جزئيًا (30 / عبوة)

The threading’s nice and clean, so they drove in without any binding when I bolted down some equipment mounts. The 30-count pack of 7/8-9s feels like solid-grade steel for the price, and the partial thread gave me the grip I needed.

Used these on a farm gate hinge repair—the 7/8-9 thread grabbed tight in the existing nut without any stripping. The partial threading made it easy to start by hand before wrenching down. Solid American steel that didn't bend under the weight of the gate.

Installing these on a heavy piece of equipment and the partial threading really helped with alignment—no stripping the threads during tightening. They’re solidly made and the hex head gave a perfect grip with my socket.
