براغي رأس سداسي 1-1/4-7 X 5-1/2" | صنع في الولايات المتحدة | سبائك فولاذ PFC9 زنك أصفر (6 / عبوة)

The thread pitch on these is perfect for the heavy equipment I was repairing, and the hex head gave my socket wrench a solid grip. I've used cheaper bolts before that stripped out, but these seem built to last with that alloy steel.

These bolts fit perfectly for a repair on my old milling machine, and the hex head took a socket wrench well without stripping. The yellow zinc coating on the PFC9 alloy steel gives them a nice finish for outdoor use.

Threads were clean and the yellow zinc finish looks properly done, no burrs or flaking. The head size grabbed my socket perfectly, so these should hold up fine on the assembly jig I’m repairing.
