Vlier DBML10A Threaded Ball Plunger M10 X 1.5

Product Description

The VLIER DBML10A is a threaded ball plunger designed for indexing, positioning, and light detent applications in industrial assemblies. The plunger body is steel with a zinc-plated finish, and the ball is nylon, making it suitable for use where a softer contact point is needed to avoid marring mating surfaces. The M10 x 1.5 thread installs directly into a tapped hole. Initial end force is 1.8 pounds and final end force is 3.37 pounds, giving technicians a predictable engagement feel. Ball diameter is 0.236 inches with a maximum ball reach of 0.079 inches. Machinists, toolmakers, and assembly technicians are the primary installers of this type of component.

This ball plunger is suited for light-duty positioning and detent functions in jigs, fixtures, tooling plates, and machine assemblies. The nylon ball makes it appropriate for applications where the contact surface must not be scratched or dented. The M10 x 1.5 thread is a standard metric coarse thread widely used in European and metric-dimensioned equipment. The purple color code identifies this specific spring force range within the product line for quick visual identification during assembly or maintenance.

Key Features

• Nylon ball provides non-marring contact for sensitive mating surfaces
• Steel body with zinc-plated finish for corrosion resistance
• 1.8 pounds initial end force and 3.37 pounds final end force for consistent detent engagement
• 0.236 inches ball diameter with 0.079 inches maximum ball reach
• Purple color code for fast visual spring-force identification

Compatibility

Designed as a standard metric threaded ball plunger for use in any tapped M10 x 1.5 hole in industrial jigs, fixtures, tooling, and machine assemblies requiring a light-duty non-marring detent point.

Installation Notes

Installation requires a properly tapped M10 x 1.5 through or blind hole in the mating component. Ensure the workpiece is de-energized or depressurized before installing or replacing plungers in active fixtures or machine assemblies. Use an appropriate wrench on the hex body to avoid damaging the plunger or the nylon ball during installation. Do not overtighten, as this can distort the body and restrict ball movement.
