مسامير رأس سداسية 5/8-11 × 7 بوصة | صناعة أمريكية | فولاذ سبائك PFC9 زنك أصفر (25 / عبوة)

The yellow zinc coating on these 5/8-11 screws is even and consistent across all 25 pieces. They threaded smoothly into my equipment frame with no binding, and the hex heads gave my socket wrench a solid grip. Exactly what I needed for a reliable industrial assembly.

Installed these in a heavy-duty support frame and the 7-inch length was spot-on for threading through thick steel. The yellow zinc coating looks clean and seems like it'll resist rust just fine.

I tightened down a stubborn bracket on my press with these and the hex head gave me a solid grip without stripping. The threads cut cleanly into the tapped hole, and the yellow zinc coating seems tough enough to resist rust in my shop.
