Vlier M53P Threaded Spring Plunger 10-32 Steel Locking

Product Description

The VLIER M53P is a stubby threaded spring plunger designed for precision positioning and detent applications in restricted-space environments. The M53P features a 10-32 thread with a thread length of 0.468 inches and a maximum plunger diameter of 0.093 inches, making it suitable for installations where clearance is limited. Initial end force is 0.75 pounds, with a final end force of 2.5 pounds. Both the body and nose are constructed from steel, providing durability under repeated cycling. A locking element is included to secure the plunger in place once installed. Mechanical assemblers, toolmakers, and precision equipment technicians are the typical installers of this component.

The M53P is suited for high end-force applications where available installation space is at a premium. Its stubby profile and compact 0.468-inch body length allow it to be used in jigs, fixtures, machine tool components, and precision assemblies where standard-length spring plungers would not fit. The locking element makes it appropriate for applications subject to vibration or movement that could cause an unlocked plunger to back out over time.

Key Features

• 10-32 thread size with 0.468-inch thread length for direct installation into tapped holes
• Stubby plunger profile engineered for restricted-space applications
• 0.75 pound initial end force and 2.5 pound final end force for positive detent action
• Steel body and steel nose for strength and wear resistance
• Integrated locking element prevents backing out under vibration
• 0.065-inch plunger projection suitable for light-duty positioning detents

Compatibility

Designed as an OEM-style replacement or direct-fit component for assemblies requiring a 10-32 threaded spring plunger with a stubby body profile and locking element.

Installation Notes

Installation requires a properly tapped 10-32 threaded hole. The locking element should be engaged after the plunger is threaded to the correct depth to prevent loosening during operation. Power down or de-energize any associated equipment before servicing the assembly. Use appropriate thread engagement practices and avoid over-torquing, which can damage the locking element or plunger nose.
