براغي رأس سداسية M14-2 × 55 مم | فولاذ درجة 8.8 عادي | ملولبة جزئيًا (50 / عبوة)

I needed these for a heavy equipment repair and the class 8.8 steel handled the torque without any issues. The hex head fit my socket perfectly, making installation fast and straightforward. Exactly what I expected for industrial fastening.

The partially threaded design was exactly what I needed for clamping a large steel frame, and the 55mm length gave plenty of grip without bottoming out. These bolts threaded smoothly into my tapped holes with no binding.

Picked up a pack for a jig I'm building on a metal frame, and the partially threaded shaft let me get a solid bite without binding up. They drove in evenly with just a standard socket, and all fifty heads looked clean out of the bag.
