براغي رأس سداسية M16-1.5 × 140 مم | فولاذ فئة 10.9 غير معالج | خيط جزئي (25 / عبوة)

The partially threaded design made it easy to secure a motor mount without the threads binding in the blind hole. These bolts feel rock-solid for the price.

I used these to bolt down a heavy press in the shop, and the 140mm length was just right for going through the frame and into the concrete anchor. The hex head gave a solid grip for my impact wrench without any stripping.

The threads are cut clean and the partial threading grabbed perfectly for my equipment frame build—no wobble or cross-threading even under heavy torque. Class 10.9 steel feels seriously robust, and the hex head seats deep with a standard socket. Exactly what I needed for a solid, permanent joint.
