Vlier SSM63 Threaded Spring Plunger 5/8-11 Stainless Steel

Product Description

The VLIER SSM63 is a stubby threaded spring plunger designed for applications requiring high end force in restricted space. The body and nose are both stainless steel construction, offering corrosion resistance in demanding environments. The plunger features a 5/8-11 thread with a thread length of 1.062 inches and a maximum plunger diameter of 0.31 inches. It delivers an initial end force of 2 pounds and a final end force of 8.5 pounds, making it well suited for indexing, positioning, and detent functions where a firm, reliable spring load is needed in a compact footprint. Licensed maintenance technicians and machine assemblers install this component in tooling, fixtures, and mechanical assemblies.

The SSM63 is intended for use in high end force, restricted space applications. Its stubby plunger length type and compact overall body length of 1.062 inches allow it to fit into tight clearance locations where a standard-length spring plunger would not. Typical install scenarios include machine tool fixtures, jigs, production tooling, and industrial equipment assemblies where precise detent or positioning action is required. The stainless steel body is appropriate for environments where moisture, cleaning agents, or mild corrosives are present.

Key Features

• Stubby plunger length type for use in restricted space applications
• 5/8-11 thread size with 1.062 inch thread length for secure installation
• 2 pound initial end force and 8.5 pound final end force for firm detent action

• Maximum plunger diameter of 0.31 inches and projection of 0.215 inches
• No locking element, allowing straightforward removal and adjustment

Compatibility

Designed as an OEM-style replacement or direct-fit component for threaded spring plunger applications requiring a 5/8-11 thread in high end force, restricted space installations.

Installation Notes

Installation is typically performed by machine builders, maintenance technicians, or tooling assemblers. Power down or de-energize any machinery before installing or removing this plunger. Use appropriate thread engagement practices and ensure the mating tapped hole meets the 5/8-11 thread specification before installation. Do not exceed the rated final end force or over-compress the plunger beyond its designed projection range.
