براغي رأس سداسي M20-1.5 X 150mm | فولاذ فئة 10.9 عادي | خيط جزئي (10 / عبوة)

The partially threaded design made installing these on a large jig much easier than fully threaded bolts, and the hex head gave my socket wrench a solid grip without slipping.

Picked up a pack for a heavy equipment repair job, and the 10.9 grade steel held up perfectly under full torque without any deformation. The partially threaded shank made alignment much easier than dealing with fully threaded bolts in tight spots.

The threads cut clean and the hex head seated perfectly with a 24mm socket, no stripping even under heavy torque. For the price of ten, these class 10.9 bolts feel like they'll outlast the machine they're holding together.
