براغي رأس سداسية 5/8-11 × 1-3/4 بوصة | صناعة أمريكية | سبيكة فولاذ PFC9 مطلي بالزنك الأصفر (25 / عبوة)

The hex heads on these cap screws seated perfectly with a socket wrench, and the yellow zinc coating looks durable. They fit my fixture assembly work nicely, and being US-made gives me confidence in the steel quality.

Installed these on a tractor PTO adapter and the fine thread seated perfectly without any wobble. The yellow zinc coating is already holding up better than the black oxide bolts I used last time.

Installed these on a heavy-duty press fixture at work, and the hex head seated perfectly with a socket wrench. The yellow zinc coating gives them a solid, uniform finish that should hold up well in our shop.
