Vlier S48A Threaded Spring Plunger 6-32 Steel Body

Product Description

The VLIER S48A is a threaded spring plunger designed for positioning, indexing, and light-duty locking applications in mechanical assemblies. It features a 6-32 thread size with a 3/8-inch thread length and a standard-length steel body. The plunger tip diameter ranges from 0.044 to 0.045 inches, with a 1/16-inch projection beyond the body face. Initial end force is 1 pound and final end force is 1.6 pounds. Machinists, toolmakers, and maintenance technicians install this type of component in fixtures, jigs, and precision equipment where repeatable spring-loaded detent action is required.

The S48A suits applications in light mechanical assemblies where a compact, threaded spring plunger is needed to provide consistent detent force. The 6-32 thread size makes it compatible with standard tapped holes in aluminum, steel, and plastic assemblies. Typical uses include panel alignment, drawer detents, and fixture registration in industrial and commercial equipment. The all-steel construction handles moderate wear conditions in production and maintenance environments.

Key Features

• 6-32 thread size with 3/8-inch thread and body length for compact installation
• Plunger projection of 1/16 inch for controlled detent engagement
• Initial end force of 1 pound and final end force of 1.6 pounds for light-duty indexing
• Plunger diameter range of 0.044 to 0.045 inches for precise fitment
• Steel body and nose material for durability in production environments
• No locking element - free-spinning installation for easy torque adjustment

Compatibility

Designed as a standard threaded spring plunger for use in any assembly accepting a 6-32 tapped hole where a spring-loaded detent or positioning element is required.

Installation Notes

Technicians and machinists install threaded spring plungers using a hex key or flat-blade screwdriver in a pre-tapped hole of the correct thread size and depth. Power down or de-energize any equipment before servicing assemblies containing spring plungers. Avoid overtightening, as this compresses the spring beyond its working range and reduces detent performance. Thread engagement depth should be verified against the 3/8-inch body length to ensure full thread contact.
