The Series 14 Long Inserts are the longer version of the Series 14 Short Inserts to provide higher resistance to torque and pull-out. The Series 14 Long Insert is designed for use in tapered holes which facilitates proper seating and maximizes the surface contact between the Insert and hole wall prior to the application of heat or ultrasonic vibration. The Series 14 Long Insert is available in metric threads ranging from M2 to M8.
