براغي رأس سداسي 9/16-12 X 3-1/2" | صنع في الولايات المتحدة | درجة L9 سبيكة فولاذ زنك أصفر | خيط جزئي (25 / عبوة)

I had to torque these down pretty hard for a heavy-duty repair, and the hex head held without stripping at all. The yellow zinc finish looks clean too.

These threaded all the way in smoothly with a standard wrench, and the yellow zinc finish seems like it’ll resist rust well. Perfect for securing heavy equipment on my shop press.

The hex head seated perfectly with a socket wrench on our press frame, and the yellow zinc finish still looks clean after a week of oily shop work. Threads engaged smoothly even with the partial thread section, which made alignment a lot easier than fully threaded bolts would have been.
