Press-In Inserts are designed to be pressed into the plastic hole without melting the plastic prior to installation. Press-In Inserts offer rapid installation with no specialized equipment and achieve good overall joint performance

The Series 51 Inserts are the headed version of the Series 50. The head provides a larger bearing surface for the mating assembly is also suitable for pull-through applications where high pull-out force is a requirement. Series 51 Inserts are available in thread sizes ranging from M2 to M8.
