براغي رأس سداسية M4-0.7 X 16mm | فولاذ فئة 8.8 غير معالج | خيط كامل (2250/عبوة)

Put these on an assembly jig and the hex head let me use a socket driver to get a consistent torque across all two hundred fasteners. The 8.8 steel feels solid and the threads were clean on every single screw.

I was replacing a mis-threaded M4 mount on a small conveyor bracket, and these caps cut the job in half. The 8.8 steel feels solid—no bending or stripping when I torqued them down.

Finally—a bulk pack where the hex heads are actually uniform and the M4-0.7 thread catches cleanly the first time. These class 8.8 steel cap screws are holding up well in our equipment assembly, no stripping.
