براغي رأس سداسية ثقيلة مقاس 3/4-10 × 6-1/2" | ASTM A193 B7 فولاذ سبائكي عادي | خيط جزئي (45/عبوة)

The threading is clean and the alloy steel feels solid—no burrs or off-spec threads on any of the forty-five. I torqued a few to spec on a jig frame and they seated perfectly, so I’ve already ordered another pack for the next job.

Installed these on a compressor baseplate and the partial threads saved me time aligning washers. The 3/4-10 threads bit cleanly into the tapped holes, and the B7 alloy feels noticeably tougher than the old bolts I replaced.

Needed these for a pump coupling and the partial threading grabbed perfectly without bottoming out early. The alloy steel feels substantial and the hex head took a wrench without any rounding.
