براغي رأس سداسي ثقيل 3/4-10 × 8-1/2" | ASTM A193 B7 سبيكة فولاذ عادي | ملولبة جزئيًا (35 / عبوة)

The threads are clean and consistent all the way down, and the 8-1/2 inch length gives me plenty of bite on heavy equipment mounts. No burrs or rough spots on these, which saved me some filing time.

The threads are clean and sharp all the way down, which made seating these against the machine frame a breeze. I’ve torqued a few of them to spec and the B7 alloy holds without any give so far. Exactly what I needed for a heavy equipment repair.

The packaging was sturdy, so all 35 bolts arrived without any damage. Threaded them into a heavy pump base and they seated perfectly with no binding.
