JG Retractable Plungers | Precision Spring-Loaded Positioning Components

JG Retractable Plungers—also known as indexing plungers or pull-pin plungers—are spring-loaded components designed for repeatable positioning, locking, alignment, and quick changeovers in fixtures and industrial equipment (application dependent). The retractable pin can be pulled back to disengage, allowing components to slide, rotate, adjust, or be removed, then released to re-engage with a locating hole for consistent positioning.
