براغي رأس سداسي 3/4-16 × 4-1/2" | صناعة أمريكية | فولاذ سبائك PFC9 مطلي بالزنك الأصفر (20 / عبوة)

These bolts fit perfectly into the mounting brackets on my hydraulic press, and the yellow zinc coating looks like it’ll hold up well against oil and grime. I was glad to see they come from a US mill, since the threads were clean and consistent right out of the box.

The hex cut on these bolts grabbed my socket perfectly without any slipping. Threads ran smooth and clean into my press frame, exactly what I needed for that repair.

Needed these for a heavy machinery repair and the hex head seated perfectly with a socket wrench. The USA-made alloy steel feels solid, and the yellow zinc coating should hold up fine even around some grime.
