The Jergens Steel Ball Plunger, part number 10980, features a thread size of M8 x 1.25 and is designed for applications requiring reliable spring-loaded engagement. It has an initial force of 2.70 kg and a final force of 7.65 kg, making it suitable for various fastening tasks. The body is constructed from low carbon steel with a black oxide finish, while the ball is made from 440 stainless steel, ensuring durability and resistance to corrosion. The spring is composed of 17-7 PH stainless steel, contributing to the overall longevity of the product. This plunger includes a patch-style locking element for secure retention. For optimal performance, it is recommended that the tapped hole be countersunk at least 0.030" to 0.045" larger than the major diameter of the plunger.
Jergens Ball Plungers are made under extremely accurate machine controls and rigid inspection procedures. Accurate spring alignment is maintained by using a stainless rivet with a long shank on larger sizes of our Ball Plungers. This precisely positions the spring for more accurate ball travel and provides positive control of spring pressure. By minimizing the lining pin head thickness, we are able to use the longest possible springs.
