Vlier DB50A Threaded Ball Plunger 8-32 Steel Nylon Ball

Product Description

The VLIER DB50A is a threaded ball plunger designed for controlled end-force applications in mechanical assemblies. It features a steel body with a nylon ball and an 8-32 thread size. The body measures 0.344 inches in length with a ball diameter of 0.094 inches and a maximum ball reach of 0.025 inches. Initial end force is 0.5 pounds and final end force is 1.25 pounds. The zinc-plated finish provides corrosion resistance for general industrial use. Technicians and assemblers install this plunger into tapped holes to provide repeatable detent or positioning force in jigs, fixtures, and precision mechanical components.

The DB50A is suited for light-duty controlled end-force applications in manufacturing, tooling, and assembly environments. Its compact 8-32 threaded body fits into standard tapped holes and delivers consistent, low-force detent action. Common applications include indexing mechanisms, panel latches, tool holders, and fixture positioning where a defined but light resistance is required. The purple color code aids in field identification when multiple plunger specifications are used in the same assembly or kit.

Key Features

• 8-32 thread size for installation into standard tapped holes
• Nylon ball provides smooth, low-wear detent action
• Steel body with zinc-plated finish for general corrosion resistance
• Controlled end force: 0.5 pounds initial, 1.25 pounds final
• Compact body length of 0.344 inches for tight-clearance installations
• Purple color code for quick visual identification among mixed plunger sets

Compatibility

Designed as a standard 8-32 threaded ball plunger for controlled end-force applications in mechanical assemblies, fixtures, and tooling that accept an 8-32 threaded insert.

Installation Notes

Install into a properly tapped 8-32 hole using a standard hex key or driver appropriate for the plunger head style. Ensure the receiving bore is clean and free of debris before threading in the plunger to prevent cross-threading or inconsistent seating. De-energize or lock out any powered equipment before servicing assemblies that contain these plungers. Do not overtighten, as this can deform the nylon ball or alter the specified end-force characteristics.
