Precision Inserts for Closed-End "Mold-In" ApplicationsMC Series: Precision Inserts for Closed-End "Mold-In" Applications.

Our MC-Series insert is designed to be molded into Plastics, Rubber & Ceramics. The insert is designed with aggressive diamond knurling that provides high resistance to tensile pull and rotational torque loads. It has a closed bottom and a controlled minor diameter which provides for accurate positioning on core pins. The "closed-end" bottom prevents plastic flow into the threads.
