براغي رأس سداسية M30-3.5 × 220mm | فئة 10.9 فولاذ مطلي بالزنك | جزئي الخيط (10/عبوة)

These partially threaded M30 bolts were exactly what I needed for a heavy-duty machinery repair. The zinc plating looks solid and the threads engaged cleanly without any binding.

The hex head on these M30 bolts gave my socket a solid grip during assembly, no slipping at all. Class 10.9 steel feels tough enough for heavy equipment, and the 220mm length fit our frame perfectly.

The partially threaded design made aligning the plates much easier than with fully threaded bolts I've used before. The hex head gives a solid grip for my impact wrench, and the zinc coating looks clean.
