Vlier M53 Threaded Spring Plunger 10-32 Steel

Product Description

The VLIER M53 is a stubby threaded spring plunger designed for precise, repeatable positioning and light-duty detent applications in restricted-space installations. It features a 10-32 thread with a body and thread length of 0.468 inches, a maximum plunger diameter of 0.093 inches, and a projection of 0.065 inches. The steel body and steel nose deliver durability in demanding environments where a compact form factor is required. Initial end force is 0.75 pounds and final end force is 2.5 pounds, making this plunger suited for high-end-force applications within a minimal footprint. Machinists, toolmakers, and mechanical assembly technicians are the typical installers.

The M53 is applied in high-end-force, restricted-space scenarios where standard-length plungers cannot fit. Typical use cases include jigs, fixtures, tooling plates, and precision mechanical assemblies where a threaded insert-style plunger is required to index, locate, or retain a component under spring tension. The stubby plunger length type makes it well-suited for shallow-bore or thin-panel installations where thread engagement depth is limited.

Key Features

• Stubby plunger length type for restricted-space and shallow-bore installations
• 10-32 threaded body with 0.468 inches thread length for secure fastening
• 0.065 inches plunger projection provides controlled, low-profile detent action
• 2.5 lb final end force supports high-end-force positioning requirements
• All-steel body and nose construction for durability in industrial environments
• No locking element - threads directly into a tapped hole for straightforward installation

Compatibility

Designed as an OEM-style threaded spring plunger for use in jigs, fixtures, tooling, and mechanical assemblies requiring a 10-32 threaded plunger with a stubby body profile.

Installation Notes

Installation is performed by threading the M53 into a tapped 10-32 hole using an appropriate driver or wrench on the body hex feature. De-energize or secure any assembly before installing or adjusting spring plungers to prevent unintended movement. Ensure the mating bore depth and thread engagement are adequate for the 0.468 inches body length before installation. Do not exceed the rated end force by staking, pinning, or otherwise restricting plunger travel beyond design limits.
