Category Details

A selection of Stainless Body and Ball with Threadlock Ball Threaded Plungers. With Long-Lok thread locking compound to prevent loosening

  • 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.
  • Items shown with Long-Lok have a dry threadlocking sealant applied to thread.
