براغي رأس سداسية M10-1.5 × 75 مم | فولاذ فئة 10.9 مطلي بالزنك | خيط جزئي (100 / عبوة)

These bolts tightened down perfectly on my tractor attachment without stripping under heavy torque. The class 10.9 rating really earns its keep during assembly.

The partially threaded shaft made installing these in my equipment frame much easier since the unthreaded portion lined up perfectly with the clearance hole. Zinc plating looks clean and hasn’t shown any rust after a few weeks in a slightly damp shop.

Bought these for a jig I’m building and the partial threading is exactly what I needed for the clamping force. They drove in clean with a socket wrench, and the zinc coating looks solid without any flaking.
