Vlier M52 Threaded Spring Plunger 10-32 Steel

Product Description

The VLIER M52 is a stubby threaded spring plunger designed for applications requiring high end force in restricted or confined spaces. The steel body and steel nose provide durability under repeated cycling. Thread size is 10-32 with a thread length of 0.468 inches and a plunger projection of 0.065 inches. Initial end force is 1.75 pounds and final end force is 6.25 pounds. The M52 is installed by maintenance technicians and precision assembly professionals working in mechanical positioning, indexing, and detent applications where space constraints rule out longer-body plungers.

This plunger suits residential and commercial mechanical assemblies, tooling fixtures, and machine components where a compact, high-force spring plunger is required. The stubby body profile allows installation in tight housings or thin panels where a standard-length plunger would not fit. Its 10-32 threaded body threads directly into a tapped hole, making installation straightforward in most metalworking and fabrication contexts.

Key Features

• Stubby plunger length type for use in restricted or confined spaces
• High final end force of 6.25 pounds for secure indexing and detent holding
• Steel body and steel nose for mechanical durability
• 10-32 threaded body with 0.468 inch thread length for standard tapped-hole installation
• No locking element - threads directly into existing tapped holes without thread-locking hardware
• Compact plunger diameter of 0.093 inches suits fine-pitch positioning assemblies

Compatibility

Designed for use in high end force, restricted space applications requiring a 10-32 threaded spring plunger with a stubby body profile.

Installation Notes

Installation is performed by mechanical assemblers or maintenance technicians using standard hand tools to thread the body into a pre-tapped 10-32 hole. Ensure the mating assembly is de-energized and at rest before servicing any spring plunger location. Do not over-torque the body, as this can damage the thread engagement or alter spring preload. Verify plunger projection clearance against mating surfaces before final assembly.
