Threaded Inserts for plastics 

Threaded Inserts for plastics provide reusable metal threads and secure tight threaded joints in thermoplastics and thermosets. These threaded inserts have more pull-out force on a mating part than a self-tapping screw in plastics. They are also designed for easy and fast installation into plastics using in-moulding, cold, heat or ultrasonic pressing.
