About
Mini indexing plungers are designed for use in thin walled sheet metal applications. They are made of a plastic knob, zinc plated steel body, 301 stainless steel spring, and 303 stainless steel plunger pin. The plungers are positioned by holding the knurled knob and retracting the pin. Once the pin is retracted, the spanner flats on the lock nut are revealed and the precision mini indexing plunger can be tightened with an open end wrench. They are available with or without the lock-out feature and come in inch (5/16”-24 TPI) and metric (M8X1.0-M16X1.5) sizes.

Indexing plungers with the lock-out feature are used in applications where the plunger must not protrude continually. To achieve this, the knob is rotated by 90° after being retracted. The head of the plunger body is provided with a suitable notch in opposite positions to prevent the plunger from accidentally slipping back into its forward position due to error or vibration. Lock-out precision indexing plungers are available with or without locknut. The locknut type is commonly used in high leverage applications where the indexing plunger needs to stay locked in a fixed position.

Precision indexing plungers without the lock-out feature are used in applications where the plunger does not have to stay retracted. The non-locking indexing plungers are often used in the medical and fitness industries for adjusting seat heights but they are most commonly used in industrial equipment for positioning and holding. We offer a version with a locknut for applications where the plunger needs to stay locked in a fixed position.
