Item # HM30 x 188E, HE Series HM30 x 188E Model Threaded Expansion Insert for Plastics On O.E.M. Fastening Systems

Request Information

Our E & HE Series threaded expansion inserts are designed to provide strong reusable threads in thermoset and other hard plastics. Expansion inserts are pressed into the plastic and expand when the assembly screw is tightened. The sharp diamond knurling provides resistance to tensile and torque loads.

Additional Information

N/A The mating screw should be designed for full thread engagement. This will allow the insert to fully expand. For best results, the boss diameters should be approximately 2-1/2 times the recommended hole size. In "through-hole" applications, the HE Series flange adds greater strength for tensile pull loads. Inserts are available with or without a flange.
