The HIHL range has been designed with a rounded crest and knurl configuration to be installed into Notch Sensitive Plastics such as 30% Glass Filled Polycarbonate. This insert reduces the stress and is available in a headed version to increase performance and aid with electrical contacts. It's designed to be installed into drilled or moulded holes using direct heat and reduces the risks associated with cracking.
