Indexing Plungers

Indexing Plungers

Indexing plungers are precision-engineered components used to accurately lock, locate, and position moving parts in machinery and equipment. They allow for quick and easy adjustments while ensuring components remain securely fixed in place during operation.

Commonly used in mechanical engineering, automation systems, jigs, fixtures, and assembly setups, indexing plungers consist of a spring-loaded pin that can be retracted and re-engaged as needed. This design enables repeatable positioning and reliable holding, improving both safety and efficiency in industrial applications.

Available in various styles — including lock-out types, pull knob, and threaded versions — indexing plungers come in materials such as steel or stainless steel for strength and corrosion resistance, with plastic or metal knobs for user comfort.
