براغي رأس سداسية مقاس 5/8-18 × 3 بوصة | صنع في الولايات المتحدة | فولاذ سبائكي PFC9 مطلي بالزنك الأصفر (25 / عبوة)

Wrenched these into a heavy press today and the threads ran clean with zero binding. The PFC9 alloy takes a beating without the head stripping out, and the yellow zinc finish still looks factory fresh after a full shift.

The yellow zinc coating on these bolts seems really uniform and thick, which is what I needed for outdoor equipment. They drove in clean with a socket and the threads caught right away.

Threaded these into a piece of heavy equipment and they seated perfectly with no binding. The hex head gave my wrench a solid grip, and the yellow zinc coating has held up well so far.
