Series 14 Short Inserts are designed for use in tapered holes. The tapered hole 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 Short Insert is available in metric threads ranging from M2 to M6.

If you don’t see what you are looking for in our standard offering (including thread size, length, quantity, etc.), please feel free to contact SPIROL directly at or call any one of our global offices for complimentary Application Engineering assistance!
