براغي رأس سداسي M12-1.75 X 180mm | فولاذ فئة 8.8 مطلي بالزنك | خيط جزئي (20 / عبوة)

The zinc plating looks uniform and the hex head seated perfectly with my socket, no rounding at all. These 180mm partially threaded bolts gave me just the right grip length for sandwiching steel brackets, and all 20 threads were clean with no burrs.

Just got these for a new jig I'm building, and the partial threading really helps seat them deep without fighting shavings. They're solid 8.8 steel and the hex head grabs my socket cleanly.

Used these to bolt down a milling machine at the shop; the partially threaded shaft gave plenty of grip for the frame. The zinc coating held up well against a little moisture in the basement.
