Versatile Spring Plungers: Ball, Retractable & Locking Pins

To simplify selection, we clarify key product differences. Spring Loaded Plunger includes diverse designs for specific needs. The Threaded Spring Plunger, for instance, has a threaded body for flexible, adjustable installation—ideal for machine design and assembly lines—with secure attachment even in high-vibration environments, paired with customizable spring forces.

For temporary locking or clamping, the Ball Plunger is ideal, featuring a metallic ball end that distributes weight and reduces wear. The Ball Plunger Screw combines this precision with threaded mounting, suitable for light-duty positioning in household and industrial equipment.

Plunger Pins and Spring Plunger Pin ensure consistent flat-surface engagement, perfect for guiding, alignment, and indexing (e.g., indexing tables, conveyors). The Index Plunger Pin offers enhanced precision for accurate machinery component alignment.

For adjustable or removable positioning, the Retractable Spring Plunger enables easy disengagement, reducing maintenance downtime. The Locking Plunger Pin has a built-in lock to secure components and prevent accidental movement, ideal for machinery guarding.
