براغي رأس سداسية M12-1.25 × 80mm | فولاذ درجة 10.9 عادي | ملولبة جزئياً (50 / عبوة)

The partially threaded shank on these M12 bolts made aligning them in a tight bracket much easier than fully threaded ones would have been. They torqued down smoothly with a socket and feel solid in the assembly.

I needed some heavy-duty bolts for a custom trailer hitch, and these M12s are exactly the right length and thread pitch. The partially threaded shaft makes alignment much easier than fully threaded ones I've used before.

The threads are clean and the hex heads fit a standard socket perfectly, which made bolting up my jig table a breeze. These 10.9 grade screws feel rock solid, and the partial threading gave me the grip I needed without bottoming out.
