1/4 Press-In Inserts
Press-In Threaded Inserts, also called Ultrasonic Inserts, are internally threaded inserts specially designed for use in hard plastics such as printed circuit boards. A common trade-name is E-Z Lok®. A special insertion tool is required that applies high-frequency ultrasonic sound waves to the insert as it is slowly pressed into a pre-drilled hole in the the plastic. The heat developed melts the surrounding plastic and locks the insert in place.
