براغي رأس سداسي M20-2.5 X 100mm | فولاذ درجة 8.8 مطلي بالزنك | خيط جزئي (20/عبوة)

Needed these for a custom jig build and the partially threaded shaft made alignment much easier. The zinc coating looks even and clean, and the threads mated smoothly with a standard M20 nut.

The hex head design gave my socket wrench a solid grip, and the zinc plating seems durable. These M20 bolts held a heavy machine frame steady during reassembly—perfect length for my project.

Put these on a piece of equipment that takes a beating, and the zinc plating hasn't flaked a bit after a month of wrenching. The partial thread makes seating them in a blind hole way easier than I expected. For the price per pack, you can't really go wrong with a solid Class 8.8 fastener.
