براغي ذات رأس سداسي ثقيل 7/8-9 × 4-3/4 بوصة | ASTM A193 B7 فولاذ سبائكي عادي | ملولبة جزئيًا (40 / عبوة)

The threads on these bolts are clean and uniform, so they threaded in smoothly without any binding. Used them for a heavy-duty press repair and they held up perfectly under the load.

These replaced some worn bolts on a press and the partially threaded length grabbed perfectly, no shaving needed. The B7 alloy feels dense and the hex heads seated without stripping. Solid set for the money.

The threading is clean and the alloy steel feels rock-solid straight out of the package—no burrs or rough edges at all. These seated perfectly into my equipment frame without any binding, which is exactly what I need for a load-bearing joint.
