Vlier M52P Threaded Spring Plunger 10-32 Steel Locking

Product Description

The VLIER M52P is a stubby threaded spring plunger designed for applications requiring high end force in restricted or confined spaces. It features a steel body and steel nose with a 10-32 thread size and a thread length of 0.468 inches. The plunger diameter measures 0.093 inches with a projection of 0.065 inches. Initial end force is 1.75 pounds, and final end force reaches 6.25 pounds. A locking element is included to secure the plunger in position after installation. This component is typically installed by mechanical assemblers, toolmakers, and precision equipment technicians working with fixtures, jigs, and positioning mechanisms.

The M52P is suited for residential and industrial equipment assemblies where space constraints prevent the use of standard-length plungers. Its stubby profile makes it a practical choice for panel assemblies, small enclosures, and tight fixture designs where a conventional spring plunger would not fit. The locking element prevents loosening under vibration, making it appropriate for dynamic or high-cycle applications where plunger retention is critical.

Key Features

• Stubby plunger length type for use in restricted spaces
• 10-32 threaded body for standard tapped-hole installation
• Steel body and steel nose construction for durability
• 1.75 pound initial end force and 6.25 pound final end force
• Integrated locking element prevents loosening under vibration
• 0.065 inch plunger projection suitable for light-duty indexing and detent applications

Compatibility

Designed as an OEM-style replacement or direct-fit component for assemblies using 10-32 threaded spring plungers in high end force, restricted-space applications.

Installation Notes

Installation requires a properly tapped 10-32 hole in the mating component. Use an appropriately sized hex key or installation tool to thread the plunger body into place without damaging the locking element. Ensure the mounting surface is clean and free of debris before installation. Disengage or de-energize any associated equipment before servicing or replacing spring plungers in active assemblies.
