براغي رأس سداسي 3/8-16 × 3/4 بوصة | صناعة أمريكية | فولاذ سبائكي PFC9 زنك أصفر (100 / عبوة)

Needed a handful for a jig I was building and the hex heads grabbed the socket perfectly. The yellow zinc coating looks clean and has held up well against some light shop use.

The yellow zinc coating on these screws is really clean and even, and the threads cut smoothly into mild steel without binding. I’ve got a dozen of them holding a heavy jig together, and they haven’t budged after weeks of vibration.

Just put these on a piece of machinery where I needed a solid grip, and the hex head grabbed my socket perfectly. The yellow zinc coating looks clean and the alloy steel feels tough, nice to have U.S. made hardware.
