Headed Expansion Insert

Series 20110 Type: HDM

HDM inserts are designed to provide strong reusable threads in most plastics including thermoset. On installation, the insert collapses as it is pushed into the receiving hole. Insertion of the screw expands the sharp diamond points of the knurl into the surface of the hole and penetrates the plastic. This provides a high resistance to torque and pullout loads. The HDM has a slot through the body, the screw is meant to enter the insert through the head. The head therefore gives additional resistance to jack out loads, where the through hole in the mating component is larger than the traditional smaller diameter non headed inserts.
