Spring Plungers & Indexing Plungers

Spring plungers and indexing plungers are mechanical components used in a wide range of machine and fixture applications.

The plunger components come in a range of types, sizes and materials to suit your every requirement. There are two main types of plungers available, each suited to various different applications.

Index Plunger (with button, knob or pull loop)

Indexing plungers are made up of a threaded body, a plunger and come with or without actuating button or ring. The nose of the indexing plunger extends which holds it in place, When the handle or lift ring is pulled back the plunger is disengaged and the plunger retracts back into the body.

Spring plungers also known as ball plungers are mechanical parts that are used to secure, position index, positively lock off and apply pressure. The compact component is made up of a ball or pin and an internal spring, all contained in a housing that resembles a grub screw.
