Threaded Inserts

The WELL-NUT® threaded insert is a flanged chloroprene bushing with a brass machine nut molded into one end. Tightening a conventional machine screw threaded in the brass nut causes the insert to expand, making a secure fastening.

The JACK NUT® threaded insert is an economical blind fastener designed for assembly line use in thin, soft, or brittle materials. When tightened, the body collapses to form four legs which grip the inside of the mounting surface, leaving a permanent, reusable threaded insert.

Dodge® offers a full line of threaded inserts for plastics including brass inserts in various types and styles to suit almost any insert application in plastic. Inserts can be installed using virtually all methods of installation including ultrasonic welding, hot or cold press-in, mold-in, and self-threading.
