براغي رأس سداسية M14-1.5 × 70 مم | فولاذ فئة 10.9 مطلي بالزنك | خيط كامل (100/عبوة)

Used these to bolt down a few brackets on a press at work, and they drove in clean with a socket without a single stripped thread. The 10.9 rating gives me confidence they'll hold up under vibration.

Zinc plating looks uniform and the hex heads seated cleanly against the flange with zero galling on the threads. I used about thirty of them for a steel frame jig, and the 10.9 hardness held up well under repeated torquing.

These bolts threaded smoothly into my tractor’s hitch mounts without any binding—the Class 10.9 hardness gives me confidence they’ll hold up under heavy loads.
