Category Details

A selection of Standard Steel Ball Threaded Plungers. Items shown with Long-Lok have a dry threadlocking sealant applied to thread.

  • Spring-loaded mechanical component with a threaded body, used for locating, securing, or applying pressure.
  • When pressure is applied to the ball, it compresses the internal spring and can be temporarily pushed into the body, allowing parts to be moved, and then it springs back to its original position to hold them in place.
