براغي رأس سداسي M14-2 × 140mm | فولاذ فئة 8.8 عادي | خيط جزئي (25/عبوة)

I needed heavy-duty bolts for mounting a press, and the hex head on these made them easy to tighten with a socket wrench. The 8.8 steel feels substantial, and the partial thread let me get a solid grip in the frame without bottoming out.

The partial threading on these M14 screws made tightening them into a pre-tapped hole much easier than a fully threaded bolt. They held securely when I assembled a small jig for my drill press.

The hex heads fit my wrench perfectly with no slipping, and the partially threaded design made installing these on a heavy-duty jig a breeze. For the price of a 25-pack of class 8.8 steel, these are solid.
