Vlier SSS49 Threaded Spring Plunger 6-32 Stainless Steel

Product Description

The VLIER SSS49 is a standard threaded spring plunger designed for light-duty positioning, indexing, and detent applications in mechanical assemblies. The body and nose are both constructed from stainless steel, making it suitable for environments where corrosion resistance is required. It features a 6-32 thread size with a 17/32 inch thread length and body length. The plunger diameter ranges from 0.044 to 0.045 inches, and the nose projects 1/16 inch beyond the body. Initial end force is 0.5 pounds and final end force is 1.5 pounds. This part is installed by machinists, maintenance technicians, and mechanical assemblers working on precision equipment.

The SSS49 is used in light mechanical assemblies where a spring-loaded plunger is needed to provide repeatable positioning or detent resistance. Typical applications include jigs, fixtures, machine tool components, and instrumentation housings. The 6-32 thread size suits small-scale assemblies where space is limited and low end forces are required. No locking element is present, making installation and removal straightforward in standard tapped holes.

Key Features

• 6-32 thread size with 17/32 inch thread and body length
• Stainless steel body and nose for corrosion resistance
• Plunger diameter: 0.044 to 0.045 inches with 1/16 inch projection
• Initial end force of 0.5 pounds, final end force of 1.5 pounds
• Standard plunger length type with no locking element

Compatibility

Designed as an OEM-style replacement or direct-fit component for mechanical assemblies requiring a 6-32 threaded spring plunger with standard plunger length and stainless steel construction.

Installation Notes

Installation is performed by machinists or mechanical technicians using a standard hex key or driver matched to the plunger body. The receiving assembly must have a properly tapped 6-32 hole to specified depth before installation. Ensure the assembly is de-energized and unpressurized before servicing any components in the surrounding mechanism. Do not overtighten, as the small thread size is susceptible to galling in tapped steel or aluminum bores.
