Vlier PRSN625 Pull Ring Plunger 5/8-11 Steel

Product Description

The VLIER PRSN625 is a non-locking pull ring plunger with a 5/8-11 threaded body, designed for use in indexing, positioning, and light-duty locking applications across industrial machinery, fixtures, and fabricated assemblies. The steel construction delivers durability in demanding environments. End force ranges from 1.25 pounds initial to 5 pounds final, providing controlled resistance appropriate for repeatable positioning tasks. The 0.38-inch diameter plunger extends 0.44 inches of projection, and the overall body length is 1 inch. Installers working with jigs, fixtures, tool holders, or mechanical subassemblies will find this plunger a direct fit for standard threaded mounting holes.

The PRSN625 suits light industrial and mechanical assembly applications where a manually retractable, non-locking plunger is required. The pull ring design allows the operator to retract the plunger by hand without tools, making it well-suited for production fixtures, assembly jigs, positioning stops, and panel hardware where frequent operator interaction is expected. The 5/8-11 thread size is compatible with standard tapped holes in steel, aluminum, and fabricated frames commonly found in manufacturing and machine-tool environments.

Key Features

• Non-locking pull ring design allows tool-free manual retraction
• 5/8-11 thread for direct installation into standard tapped holes
• 1.25 pound initial to 5 pound final end force for controlled positioning resistance
• Steel construction for durability in industrial environments
• 0.44-inch plunger projection with 0.38-inch plunger diameter
• 0.62-inch hex for wrench-assisted installation and torque control

Compatibility

Designed as an OEM-style replacement or direct-install spring plunger for industrial fixtures, jigs, and mechanical assemblies requiring a 5/8-11 threaded non-locking pull ring plunger.

Installation Notes

Installation is performed by threading the PRSN625 into a pre-tapped 5/8-11 hole using the 0.62-inch hex for wrench engagement. Ensure the mating threaded bore is clean and free of debris before installation. De-energize or lock out any powered equipment before servicing assemblies that incorporate this plunger. Do not exceed the rated end force range by substituting springs or modifying the plunger body.
