براغي رأس سداسي ثقيل 3/4-10 × 3" | ASTM A193 B7 سبيكة فولاذية عادي | ملولبة جزئيًا (80 / عبوة)

The threads on these 3/4-10 bolts are very clean and started easily without any binding. I used them to mount a heavy conveyor bracket, and the plain finish held up fine during installation. Solid purchase for the price on a 80-pack.

The partially threaded length is exactly what I needed for a tight fit on a jig frame, and the B7 alloy has held up without any give under heavy loads. Threads were clean and started easily, no chasing required. Pack of 80 means I've got spares for the next couple of jobs.

Replacing some worn bolts on a press brake, these B7s threaded in smoothly without any binding. The 80-pack is a solid value for how much work you can get done.
