We manufacture custom OEM brass inserts that will work and hold under critical condition. Press-fit, Heat set, molded-in, ultrasonic we have cut thousands of them. Some parts ship to USA, some ship to consumer connectors in Germany and some other may ship to Europe for auto line.

Whether it is a Brass Threaded Insert, Brass Molding Insert, or OEM custom Brass Insert for plastic molding, we cut them with real precision knurl grip, clean thread and tight tolerance. Our inserts are not just good on paper but they work when parts hit the press.
