The Series 30 Short has the exact same body style as the Series 29 Short - with the addition of a head. The Series 30 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. The generous pilot facilitates installation into the hole. The head provides more bearing surface for the mating component, preventing jack-out. The Series 30 Short Headed Insert 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!
