The Series 20 Short Insert has the exact same body style as the Series 19 Short - with the addition of a head. The slightly tapered body is designed for use in straight holes to yield maximum performance with low radial stress. Seating and installation are facilitated with a pilot and a tapered knurl and groove design. The head provides more bearing surface for the mating component to prevent jack-out. The Series 20 Short Headed Insert is available in inch threads ranging from 2-56 up to ¼-20.

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