براغي ذات رأس سداسي M8-1.25 × 170 مم | درجة 8.8، فولاذ عادي | سن لولبي جزئي (250/عبوة)

Finally got these installed on a conveyor jig I've been tweaking, and the Class 8.8 steel feels solid under heavy torque without any stripping. The 170mm length was perfect for my thick bracket setup, and the hex heads grabbed my socket wrench nicely.

The partially threaded design made these perfect for securing a heavy base plate where I needed full grip at the tip but clean threads up top. The hex head seated perfectly with a standard socket, no stripping even under high torque.

I've been working on a custom equipment stand and these M8 x 170mm hex heads torqued down perfectly without stripping, the 8.8 steel feels solid. The partially threaded length gave me just the right grip in the frame.
