براغي رأس سداسي 3/8-24 × 1-1/4" | صناعة أمريكية | فولاذ سبائك Grade L9 مطلي بالزنك الأصفر | كامل الخيط (100/عبوة)

I was replacing bolts on a heavy-duty press and these hex heads seated perfectly with a socket wrench, no slipping at all. The yellow zinc coating looks tough and uniform across all 100 pieces.

These threads are dead straight and the yellow zinc finish is uniform across all 100, so they don’t gall when I’m torquing them down on my press tooling. The fully threaded shaft grips the full length of the nut, which honestly beats the shoulder bolts I was using before.

Installed these on a milling machine yesterday and the hex head grabbed the wrench perfectly, no rounding. The yellow zinc finish is nice and even across all 100 bolts.
