M12-1.25 X 55mm براغي رأس سداسي | فولاذ فئة 8.8 عادي | جزئي الخيوط (100 / عبوة)

Needed a batch of these for a project, and the hex head design made them easy to grip with a socket wrench. The partial threading down the shaft lined up perfectly in my jig, and not one bolt stripped during assembly.

These bolts torqued down smoothly with a socket wrench and held a heavy jig frame tight without any give. For a hundred pieces, the threads were all clean and consistent out of the box.

Took a chance on these for a machinery repair and the partial threads grabbed perfectly in the blind hole. The hex heads are crisp, no rounding with a socket, and all 100 came clean without a single burr. Solid buy for the price.
