براغي رأس سداسي 7/16-14 × 3/4 بوصة | صنع في الولايات المتحدة | PFC9 فولاذ سبائك أصفر زنك (1200 / عبوة)

I've been using these on our production line fixtures and the yellow zinc finish is holding up well even with daily wrenching. They thread smoothly into tapped holes without any binding, which saves time during changeovers.

Third order of these for our shop floor, and the yellow zinc coating on the PFC9 alloy steel is holding up way better than the cheaper bolts we used to buy. The hex heads are crisp, so a 12-point socket grabs them every time without rounding off.

Installed these on a press rebuild yesterday — the hex heads let me torque them down precisely with a deep socket. No stripped threads or warped heads so far, which is exactly what I needed for heavy-duty use.
