براغي غطاء رأس سداسي 3/8-24 × 2-1/4 بوصة | صناعة أمريكية | فولاذ سبائكي PFC9 مطلي بالزنك الأصفر (50 / عبوة)

I’ve been using these to rebuild a piece of shop equipment, and the threads cut cleanly without any binding. The hex heads are exactly the right size for a standard socket, and the yellow zinc finish has a nice, even color.

The yellow zinc finish is holding up great in our shop environment without any signs of rust after a few weeks. Threads were clean and started easily by hand in my milling machine's table.

These bolts fit perfectly into our assembly jig, and the hex head grabbed the socket without any slipping. The yellow zinc coating looks uniform and clean, which is a nice bonus for a fastener.
