براغي رأس سداسية مقاس 7/16-14 × 1" | صناعة أمريكية | سبائك فولاذية درجة L9 بطلاء زنك أصفر | ملولبة بالكامل (100/عبوة)

Pulled these out of the package and they're spot-on for rebuilding a hydraulic press table. The yellow zinc finish is even and the hex heads engage perfectly with a 7/16 socket.

Had to replace some worn bolts on an industrial conveyor and these hex heads seated perfectly with a standard socket wrench. The yellow zinc coating looks like it will hold up much better than the old black oxide ones.

Started bolting down a heavy press at work with these, and the fully threaded body made it easy to get full engagement in the tapped hole. The yellow zinc finish seems tough, no chipping after torquing them in with an impact.
