The b&m-REPTO® BU is a threaded bolt for ultrasonic embedding in thermoplastics. The external thread of the bolt, which can be designed both as metric and as customer-specific, can be used for joining and assembling further components. This ensures a process-reliable and repeatable screw connection. The knurl geometry adapted to the ultrasonic embedding is essential for the later load case.
Depending on the selection of geometry and material, the b&m-REPTO® BU can be manufactured by machining or completely by cold forming. In the innovative production process using cold forming, the applied material can be used more efficiently and the thread strength can be further increased.
