Vlier DSSB47 Threaded Ball Plunger 5-40 Stainless Steel

Product Description

The VLIER DSSB47 is a threaded ball plunger designed for light-duty positioning, indexing, and detent applications in mechanical assemblies. The plunger features a stainless steel body with a nylon ball, making it well suited for environments where corrosion resistance and low marring of mating surfaces are required. It is threaded at a 5-40 size, has a body length of 0.25 inches, a ball diameter of 0.062 inches, and a maximum ball reach of 0.02 inches. Initial end force is 0.25 pounds and final end force is 0.75 pounds. Mechanical assemblers, maintenance technicians, and precision equipment builders typically install these components.

This ball plunger is used in light-load detent and positioning applications across a range of industries, including instrumentation, electronics assembly, and small mechanical devices. The nylon ball minimizes surface damage on soft mating components, while the stainless steel body provides durability in demanding environments. The 5-40 thread allows installation in compact, tight-tolerance assemblies where small-diameter fasteners are standard. It is supplied individually and is suitable for both OEM production builds and field repair work.

Key Features

• Stainless steel body for corrosion resistance in demanding environments
• Nylon ball reduces marring on delicate or soft mating surfaces
• 5-40 thread size fits compact, tight-tolerance assemblies
• 0.25 lb initial end force and 0.75 lb final end force for light-duty detent applications
• Ball diameter of 0.062 inches with a maximum ball reach of 0.02 inches
• Zinc-plated finish with purple color code for quick visual identification

Compatibility

Designed as an OEM-style replacement or production component for mechanical assemblies requiring a 5-40 threaded ball plunger with a stainless steel body and nylon ball.

Installation Notes

Installation is performed by mechanical assemblers or maintenance technicians using a standard hex key or screwdriver appropriate for the 5-40 thread. Ensure the mating threaded hole is clean and properly tapped before installing. Do not overtighten, as the small thread size and compact body can be damaged by excessive torque. Power down or de-energize any associated equipment before servicing assemblies that include this component.
