The metric Series 20 Long series has the exact same body style as the metric Series 19 Long - 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, preventing jack-out. The Series 20 Long Headed Insert is available in metric threads ranging from M2 up to M8.

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!
