About Threaded Inserts for Plastics

Threaded inserts give a plastic part a durable metal thread. Drive a screw straight into a moulding and the thread wears a little every time the part is serviced. Fit an insert and you get a thread that stands up to repeated assembly, higher torque and pull-out loads the plastic could never handle on its own. Inserts can be fitted after moulding by heat or ultrasonic methods, pressed in, or moulded in during the injection cycle, depending on the part and the volumes involved.

Choosing the Right Threaded Inserts for Plastics

Picking the right insert comes down to the polymer, the boss design, the installation method and the loads the joint will see in service.
