مسامير رأس سداسية ثقيلة 5/8-11 × 7-1/2 بوصة | فولاذ سبائكي عادي ASTM A193 B7 | ملولبة جزئياً (60 / عبوة)

The partially threaded length on these 5/8-11s is spot on for my equipment mounts, and the B7 alloy took my torque wrench without a hint of stripping. Sixty in the package means I've got spares for the next job, which is exactly what I needed.

The hex heads on these bolts gave my socket a solid bite without any slipping, which made tightening them down on a pump base much smoother. For a 60-piece box of 5/8-inch alloy steel fasteners this heavy, the price feels more than fair.

These threads cut cleanly into the steel plate on my press, and the hex head grabbed a socket without any wobble. The plain finish feels substantial and corrosion-free right out of the box.
