براغي رأس سداسي 1/2-20 X 2" | صناعة أمريكية | فولاذ سبائك PFC9 مطلي بالزنك الأصفر (50 / عبوة)

Finally got these to replace some worn bolts on a milling machine, and the yellow zinc finish looks exactly like the originals. Threads were clean all the way down and seated without any binding.

The hex drive was a perfect fit on my socket, and the USA stamp had me trusting the threads right away. These yellow zinc cap screws held firm on a tightening jig I built last weekend without any stripping.

The yellow zinc coating on these bolts is surprisingly durable—after tightening a dozen into a steel fixture, not a single scratch. Threads cut cleanly and the hex head fit snug in my socket. Solid buy for 50-piece pack.
