Press the insert into the hole using a squeezing action, not a sharp blow, while maintaining axial alignment to prevent tilting and exerting side loads on the boss. While designed to be cold press-fit, heat may be used to improve performance by increasing plastic flow around the barbs. Heat installation may be required for use in harder plastics. Ultrasonic vibration is not recommended for headed inserts. Drill or mold holes according to the indicated dimensions. Boss dimensions shown are for reference and may vary depending on the type of plastic and application.
