Threaded Inserts and Bolts

Threaded inserts and threaded bolts for plastics with different embedding methods

Threaded inserts and threaded bolts can be used to provide plastic components with a metallic nut or bolt thread. During the installation process, threaded inserts and threaded bolts create a form-fit connection to the plastic component by overmolding, ultrasonic or heat embedding and by screwing in inserts with external threads.

By using threaded inserts and threaded bolts, a process-safe connection between plastic components can be ensured, even with repetitive screw connections. Depending on the embedding method, the outer contour features knurls, grooves, hexagon contours or threads, which are designed to accommodate tensile and torque loads.
