The pioneer for self-tapping fastening into thermoplastics

EJOT PT® was the first screw of its kind specifically designed for self-tapping fastening into thermoplastics. For decades it has been the benchmark for reliable direct assembly into thermoplastics with application potential in numerous sectors, including automotive and medical appliances. Prior to its development, dynamically and thermally stressed components could not be fastened directly, and only subordinate components were joined using conventional or traditional methods. Designers had to rely on traditional fastening techniques such as screws with metal inserts. PT® changed all this - its design makes thin walled and flat designs achievable, with the potential to deliver material savings and reduced cycle times during injection moulding. The reliability and quality of the PT® joint and the fastening component can, therefore, translate into considerable cost savings overall.
