Thread-forming screws primarily use a trilobular shape of the thread body. In contrast to this conventional solution, the b&m-HIGHLOAD® uses a circular thread cross section that provides an additional load-bearing area.
The b&m-HIGHLOAD® is used primarily in composite structures. It is suitable for extremely high-stress component connections, whether in steel or aluminum. The special feature of this screw: Load tests have shown substantial preload forces and an extremely consistent screw setting behavior with moderate forming torque and high overtorque.
