M12-1.75 X 220mm براغي رأس سداسية | فولاذ فئة 10.9 غير مطلي | خيط جزئي (8 / عبوة)

These hex bolts are rated 10.9, so I wasn't worried about stripping the threads when torquing down a heavy machine base. The 220mm length was just right for passing through two thick steel flanges with a washer and nut to spare.

Needed a set of long, strong bolts for a heavy-duty trailer hitch install, and these M12×220mm partially threaded screws worked perfectly. The hex head gave my socket a solid bite without any slipping during torquing.

These are beefy bolts. The partial threading made it much easier to align the joint on my press bracket without fighting the threads the whole way.
