M12-1.5 X 150mm براغي رأس سداسي | فولاذ فئة 8.8 مطلي بالزنك | ملولب جزئيًا (25 / عبوة)

These were perfect for securing a heavy-duty jig I built at the shop; the partial threading gave me just the right grip depth. The hex head bites nicely with a standard socket, and the zinc coating seems tough enough for a damp environment.

Used a socket on these for a conveyor belt frame assembly and the hex head held up without stripping under high torque. The partial threading gave just the right grip length for my application.

Installed these on a heavy equipment jig and the 8.8 grade steel held torque perfectly without any stretching. The hex head gave my socket a solid bite, no stripping.
