Vlier DSBML12 Threaded Ball Plunger M12 X 1.75

Product Description

The VLIER DSBML12 is a threaded ball plunger designed for indexing, positioning, and light detent applications in mechanical assemblies. The body is machined from stainless steel with an M12 x 1.75 thread, making it suitable for installations where corrosion resistance or cleanroom-adjacent environments are a consideration. The nylon ball measures 0.315 inches in diameter and provides a maximum ball reach of 0.098 inches. Initial end force is 2.25 pounds and final end force is 4.5 pounds. Machinists, tool and die technicians, and maintenance mechanics install this type of hardware during fixture builds and equipment assembly.

This ball plunger fits standard M12 x 1.75 threaded holes and is used in jigs, fixtures, slides, and mechanical positioning assemblies across manufacturing and industrial maintenance environments. The nylon ball is appropriate for applications where metal-on-metal contact must be avoided to protect a mating surface finish or reduce noise. Body length is 0.866 inches, keeping the installed profile compact in tight-clearance assemblies. This part is sold individually with a minimum order quantity of one.

Key Features

• Stainless steel body for corrosion resistance in demanding environments
• Nylon ball minimizes surface marking and reduces contact noise
• M12 x 1.75 thread for direct installation into standard metric threaded holes
• 2.25 pounds initial end force and 4.5 pounds final end force for consistent, repeatable detent feel
• 0.098 inches maximum ball reach suits shallow-engagement positioning applications
• No locking element, allowing straightforward thread-in installation and removal

Compatibility

Designed as a direct-fit threaded ball plunger for standard M12 x 1.75 metric threaded holes in jigs, fixtures, and mechanical positioning assemblies.

Installation Notes

Installation requires a correctly tapped M12 x 1.75 threaded hole in the mating component. Torque the plunger body using an appropriate hex tool or wrench to seat it fully without damaging the nylon ball. Ensure the assembly is de-energized or depressurized before servicing any fixture or machine component that houses this plunger. Verify ball travel clearance in the mating slot or detent before final assembly.
