Vlier DSBMH12N Threaded Ball Plunger M12 X 1.75

Product Description

The VLIER DSBMH12N is a threaded ball plunger with an M12 x 1.75 thread size, designed to provide controlled positioning, indexing, and light detention in mechanical assemblies. The body is machined from stainless steel, and the ball is nylon, making this plunger suitable for applications where corrosion resistance and non-marring contact are both required. It delivers an initial end force of 16.86 pounds and a final end force of 25.85 pounds. The body length is 0.866 inches, with a maximum ball reach of 0.098 inches. A locking element is incorporated into the design to secure the plunger in the threaded bore during service. This component is installed by mechanical assemblers, toolmakers, and maintenance technicians.

The DSBMH12N is suited for use in fixtures, jigs, tooling plates, and general industrial machinery where a repeatable spring-loaded detent point is needed. The nylon ball resists marring on softer mating surfaces, making it appropriate for positioning applications where surface finish on the mating part must be preserved. The M12 x 1.75 thread allows installation into standard metric-tapped holes found in a wide range of production and automation equipment.

Key Features

• M12 x 1.75 thread for installation into standard metric-tapped bores
• Stainless steel body provides corrosion resistance in washdown or humid environments
• Nylon ball delivers non-marring contact on mating surfaces
• Initial end force of 16.86 pounds and final end force of 25.85 pounds for reliable detent action
• Maximum ball reach of 0.098 inches for precise positioning depth
• Integrated locking element keeps the plunger secured in the threaded bore
• Color code: Purple for quick field identification

Compatibility

Designed for installation into M12 x 1.75 metric-tapped holes in fixtures, jigs, tooling plates, and industrial machinery requiring a spring-loaded ball detent or positioning element.

Installation Notes

Install using a wrench or hex tool sized for the plunger body flat - de-energize or lock out any associated machinery before servicing detent components in automated equipment. Thread engagement should be sufficient to fully capture the locking element and seat the body flush with or below the mounting surface as the application requires. Do not over-torque the body, as this can deform the locking element or restrict ball travel. Confirm ball reach and force values are appropriate for the mating detent geometry before finalizing installation.
