Jergens 27322 Threaded Spring Plunger 8-32 Steel

Product Description

The JERGENS 27322 is a standard threaded spring plunger designed to provide controlled, spring-loaded positioning and indexing in mechanical assemblies. It features an 8-32 thread size with a 5/8-inch thread length and a maximum plunger diameter of 0.07 inches. The steel body and steel nose deliver durability in industrial and light manufacturing applications. A locking element is included to prevent the plunger from backing out under vibration or repeated cycling. Initial end force is 0.7 pounds and final end force is 2.3 pounds, giving the installer predictable engagement and release characteristics. This plunger ships in a quantity of one and is sized for precise fitment in standard tapped holes.

This spring plunger is suited for use in fixtures, jigs, tooling plates, and machine components where repeatable part positioning or detent action is required. It is installed in a pre-tapped 8-32 hole and adjusted using a 5/64-inch hex key. The black finish provides basic corrosion resistance for shop-floor environments. Machinists, tool and die makers, and mechanical assembly technicians are the primary installers of this component type.

• 0.07-inch maximum plunger diameter with 3/32-inch projection
• 0.7 lb initial end force and 2.3 lb final end force for consistent detent engagement
• Locking element prevents back-out under vibration or repeated load cycles
• Steel body and steel nose for durability in industrial environments
• Black finish for basic surface protection
• 5/64-inch hex size for installation and adjustment

Compatibility

Designed as a standard OEM-style replacement or new-install threaded spring plunger for any assembly using an 8-32 tapped hole requiring spring-loaded detent or positioning action.

Installation Notes

Installation requires a properly tapped 8-32 hole and a 5/64-inch hex key. De-energize or lock out any powered equipment before servicing assemblies containing this plunger. Thread the plunger in by hand first to avoid cross-threading, then seat with a hex key. Do not overtighten, as this can damage the locking element or compress the internal spring beyond its designed range.
