Jergens 26924 Threaded Spring Plunger 1/4-20 Steel Locking

Product Description

The JERGENS 26924 is a threaded spring plunger designed for positioning, indexing, and locking applications in mechanical assemblies. It features a 1/4-20 thread with a 1 inch thread length and a steel body finished in black. The plunger nose is also steel, providing a durable all-steel construction suited for demanding industrial environments. An integrated locking element secures the plunger in place once installed, preventing loosening from vibration. Initial end force is 3 pounds, with a final end force of 13 pounds. The 3/16 inch projection and 0.119 inch nose diameter make this a standard-size plunger for light-duty detent and positioning work. Licensed machinists, toolmakers, and maintenance mechanics typically install this type of hardware.

The 26924 is suited for use in jigs, fixtures, tooling plates, and machine components where repeatable positioning or detent action is required. The 1/4-20 thread is a common size in both inch-standard tooling and general fabrication, making this plunger a versatile fit across a wide range of mechanical assemblies in manufacturing and industrial maintenance settings. The locking element is particularly useful in high-vibration environments where an unlocked plunger body could back out over time.

Compatibility

Designed as a standard threaded spring plunger for use in inch-system jigs, fixtures, tooling plates, and mechanical assemblies requiring 1/4-20 threaded detent or positioning hardware.

Installation Notes

Install using a 1/8 inch hex key. Ensure the mating threaded hole is clean and free of debris before installation. Engage the locking element fully to prevent the plunger body from loosening during operation. No special torque specification is required beyond snug seating with the locking element engaged.
