JG Retractable Plungers

JG Retractable Plungers | Precision Spring-Loaded Positioning Components

JG retractable plungers—often called indexing plungers or pull‑pin plungers—are spring-loaded components used for repeatable positioning, locking, and quick changeovers in fixtures and industrial equipment (application dependent). The retractable pin can be pulled back to disengage, allowing parts to slide, rotate, or be removed, then released to re-engage in a locating hole for consistent alignment. These are commonly used in modular workholding, guarding, adjustable stops, and machine setups where fast, tool-free indexing is needed.
