براغي رأس سداسي ثقيل 5/8-11 X 3" | فولاذ سبائكي ASTM A193 B7 غير مطلي | ملولبة جزئيًا (10/عبوة)

The threads cut cleanly into the existing nut without any binding, and the partially threaded section makes it easy to get a firm grip before tightening. Used these to secure the base of a shop press, and they held up perfectly under the load.

Put these on a piece of heavy machinery that had sheared the old bolts, and they held without any issue. The alloy steel feels extremely sturdy, and the flat sides of the hex head gave my wrench a solid bite.

Threaded perfectly all the way down—these 5/8-11 x 3" B7 alloy steel bolts seated smoothly in my equipment mount. No galling or binding even with a heavy torque wrench. Solid little package for the price.
