Press-In Inserts are designed to be pressed into the plastic hole without melting the plastic prior to installation. Press-In Inserts offer rapid installation with no specialized equipment and achieve good overall joint performance

The Series 51 Inserts are the headed version of the Series 50. The head provides a larger bearing surface for the mating assembly, and is also suitable for pull-through applications where high pull-out force is a requirement. Series 51 Headed Press-In Inserts are available in thread sizes 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!
