براغي رأس سداسي M16-2 X 140mm | فئة 8.8 فولاذ عادي | ملولبة جزئياً (75 / علبة)

The hex head fits a standard socket perfectly, so I could torque them down precisely without any stripping. The 8.8 steel feels sturdy enough for assembling heavy equipment frames, and the 75 count should last me through several projects.

The partially threaded design made it easy to get a solid grip when tightening these to the frame of my press, and the hex head sat flush without stripping. They held up well under high torque without any sign of bending.

These bolts worked perfectly for securing a heavy conveyor frame; the 140mm length and partial threading gave me just the right grip for that thick flange. They even came neatly packaged, and the hex heads fit a standard socket without any wobble at all.
