The Series 29 Short is designed with a wide centre knurl coupled with two smaller knurls and deep undercuts on both ends to maximize torque and pull out performance. This series is symmetrical for ease of orientation, and the generous pilot facilitates installation into the hole. The Series 29 Short is available in inch threads ranging from 2-56 up to 1/4-20.

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