براغي رأس سداسية مقاس 5/8-11 × 2-1/2 بوصة | صناعة أمريكية | فولاذ سبائكي PFC9 مطلي بالزنك الأصفر (25 / عبوة)

The yellow zinc coating on these is even and consistent across all 25 bolts, which made torquing them into an engine mount a breeze. Threads engaged smoothly right from the start, no binding or grit.

Threaded these into an old milling machine base and they seated perfectly with no wobble. The yellow zinc coating looks clean and the hex heads gave my socket a solid grip. Exactly what I needed for a heavy retrofit job.
