براغي رأس سداسي 9/16-18 X 3-3/4" | صناعة أمريكية | فولاذ درجة 8 زنك أصفر (125 / عبوة)

I was replacing some worn bolts on a heavy press and these Grade 8s handled the torque without any issue. The yellow zinc coating looks consistent and should resist rust really well.

The hex heads on these seat perfectly with a socket—no rounding or slipping even under heavy torque. I used them to bolt down a jig frame and every one of the 125 threaded cleanly without a single bad piece.

The yellow zinc finish on these looks sharp and even, and the threads were clean right out of the box. I torqued a set onto a heavy equipment mount and they held perfectly with my socket, no stripping or wobble. Solid hundred and twenty-five count for the price.
