  • Series 29 Long Symmetrical Inserts

    Series 29 Long - Symmetrical Heat / Ultrasonic (Straight Hole) Inserts - Inch

    (8)

    The Series 29 Long Insert is the longer version of the Series 29 Short Insert resulting in higher torque and pull-out resistance. Designed with a wide center knurl with two smaller knurls and deep undercuts on both ends, the Series 29 Long (and the Series 30 Long – Headed version of the Series 29 Long ) typically provides the highest torque and pull out performance within SPIROL’s Heat/Ultrasonic style Inserts designed for straight holes. This series is symmetrical for ease of orientation, and the generous pilot facilitates installation into the hole. The Series 29 Long is available in inch threads ranging from 2-56 up to 5/16-18.

    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 info@spirol.com or call any one of our global offices for complimentary Application Engineering assistance!
