Say goodbye to expensive part orientation high-volume feeding mechanisms. Our symmetrical threaded inserts for plastic can be installed either end first for faster installation (using ultrasonic or thermal equipment) and lower costs.

By decreasing outward hoop stress, symmetrical threaded inserts decrease cycle times. Their proportionally engineered design ensures that the displaced material is encapsulated by knurls and undercuts. They are designed for straight hole applications and are ideal for thin-wall applications because little stress is applied to the walls of the part.
