Spring-Loaded Plungers

New press-fit spring plungers are simple, economical, and target softer materials such as aluminum, wood, or plastic.

A sturdy shoulder on these spring-loaded plungers provides a fixed seating position and positively resists detent force. The new plungers come in light or heavy force, six sizes each, in steel or stainless steel, with a stainless or Delrin ball. They are useful when a threaded hole would be impractical and/or adjustment is not required.
