براغي رأس سداسي M20-1.5 X 90mm | فولاذ عادي فئة 10.9 | ملولبة جزئيًا (25 / عبوة)

Used these on a heavy-duty jig I’m building, and the 90mm length was exactly what I needed for the thick steel plates. The hex heads grab nicely with a socket, and the Class 10.9 steel feels tough without any burrs.

The threading is clean and the heads fit a socket perfectly—no wobble when torquing down. Used these to mount a steel jig frame and they held up great during the weld. Just wish the pack had a few extra spares.

The partially threaded design made aligning them in tight spots much easier than fully threaded bolts would have. They feel sturdy and hold up well under moderate torque.
