M12-1.5 × 55mm براغي رأس سداسي | فئة 10.9 فولاذ عادي | خيط كامل (300 / عبوة)

I needed a bulk supply for a machine rebuild, and the hex heads fit my impact wrench perfectly. The 55mm length was just right for the assembly, and the threads engaged smoothly. Solid set for the price.

Threads are clean and the 10.9 hardness is obvious when tightening with a socket—no stripping or yielding under heavy torque. The fully threaded grip makes alignment easier, and the box count was spot-on.

Swapped out some older bolts on a press setup and these seated perfectly with a wrench, no galling or thread chatter. The 10.9 grade gives me confidence torquing them down hard on vibration-sensitive joints. Came in a solid 300-count box that’ll last me a while.
