Description

This M16 Black Spring-Loaded Index Plunger is a robust, precision-engineered positioning component designed for machinery, fabrication jigs, equipment frames and industrial assemblies requiring accurate, repeatable indexing. The strong internal spring provides positive engagement of the locking pin, ensuring reliable location control even under vibration or frequent movement.

The black-finished body offers enhanced corrosion resistance and a clean industrial appearance, making it suitable for manufacturing environments, machine guards, handling equipment and adjustable mechanisms.
The ergonomic pull knob allows the operator to disengage the pin quickly for repositioning, then re-engage it securely when released—ideal for setups that require fast, manual adjustment without tools.

Built for long service life, this M16 plunger delivers dependable holding strength and smooth operation in demanding applications.
