5/8-11 × 2-3/4" براغي رأس سداسي ثقيل | ASTM A193 B7 سبيكة فولاذ عادي | خيط جزئي (25 / عبوة)

I needed these for a heavy-duty pump bracket, and the 2-3/4" length was just right for the flange thickness. The all-thread pattern on the partial threads held torque well without galling.

The threads cut cleanly and seated perfectly in my press bracket without any binding. Tightened them to spec with a torque wrench and they held firm under full load. Exactly what I needed for heavy equipment assembly.

Grabbed a pack for reattaching a pump motor bracket and the threads were clean, no galling on the first run. The partially threaded shank gave me plenty of grip length without bottoming out in the blind hole.
