براغي رأس سداسية M10-1.5 × 45 مم | فولاذ فئة 10.9 عادي | ملولبة جزئيًا (75 / عبوة)

Installed these on a heavy-duty jig I'm building and the 10.9 grade steel held torque perfectly without stripping. The 45mm length was exactly what I needed to get through the bracket and into the frame.

The partially threaded design made it much easier to start these by hand before I tightened with a socket. They feel solidly built and held together a heavy steel frame without any slippage.

I needed some sturdy fasteners for a heavy equipment frame I’m rebuilding, and these 45mm hex head bolts with their partial threading held perfectly under torque. The Class 10.9 steel feels solid, and the hex head made wrenching them in place a breeze. Exactly what I needed for this job.
