M12-1.75 X 85mm براغي ذات رأس سداسي | فولاذ فئة 10.9 عادي | ملولب جزئياً (30 / Pkg.)

Perfect thread engagement through the full 85mm length, and the hex heads are crisp enough for a socket to grab without slipping during high-torque tightening. Used these for mounting a heavy-duty bracket on my tractor and they haven't budged.

The partially threaded section grabs exactly where I need it on the flange, and the hex head takes a socket without any rounding. Used a dozen on a press frame rebuild and every one torqued down clean at 10.9 spec.

These threads are solid, no galling or stripping when I torqued them down on the equipment frame. The 85mm length with the partial thread gave me just the right grip for the joint. Pack of 30 is a good value for a job this size.
