Vlier DSSBL52P Threaded Ball Plunger 10-32 Stainless Steel

Product Description

The VLIER DSSBL52P is a threaded ball plunger designed for indexing, positioning, and light-duty detent applications in mechanical assemblies. It features a stainless steel body with a nylon ball and a zinc-plated finish. The plunger installs into a 10-32 threaded hole and provides a maximum ball reach of 0.025 inches. Initial end force is 0.5 pounds and final end force is 1.5 pounds, making it suitable for low-force, precise positioning tasks. A locking element is included to secure the plunger in place after installation. Machinists, toolmakers, and mechanical assembly technicians are the primary installers of this component.

This ball plunger is used in light industrial and precision mechanical applications where repeatable positioning or detent action is needed. Typical installation scenarios include jigs, fixtures, tooling plates, and machine assemblies requiring a compact, threaded plunger with controlled spring force. The 10-32 thread size fits standard tapped holes in metal and composite assemblies. The nylon ball minimizes surface marking on mating components, making this plunger appropriate where soft contact is required.

Key Features

• 10-32 threaded body for direct installation into standard tapped holes
• Stainless steel body with zinc-plated finish for corrosion resistance
• Nylon ball provides low-friction, non-marring contact
• Locking element secures the plunger position after adjustment
• Low force range: 0.5 pounds initial to 1.5 pounds final end force
• Compact body length of 0.513 inches suits space-constrained assemblies

Compatibility

Designed for installation into any 10-32 tapped hole in mechanical assemblies, jigs, fixtures, or tooling where a low-force ball plunger detent is required.

Installation Notes

Installation requires a properly tapped 10-32 threaded hole. Use an appropriate hex key or driver to thread the plunger body into place, then engage the locking element to prevent rotation or backing out during operation. Ensure the mating surface and threaded hole are clean and free of debris before installation. Do not overtighten, as this can damage the nylon ball or compress the internal spring beyond its rated travel.
