براغي رأس سداسية M22-2.5 × 100 مم | فولاذ فئة 10.9 غير مطلي | ملولبة جزئيًا (50 / عبوة)

These bolts really hold torque well under heavy load, and the hex head gives great purchase with a socket. The 100mm length was spot on for my steel frame jig, and the 10.9 grade feels reassuringly strong.

The partially threaded design bites in clean and leaves plenty of grip for a solid clamp on my jig. Class 10.9 steel feels seriously tough, and the hex head seats well with a socket.

The partially threaded design made installation easier than fully threaded bolts, and the hex head gripped my socket wrench well. Only issue was the packaging could be sturdier for heavy hardware like this.
