Vlier BMH12A Threaded Ball Plunger M12 X 1.75 Steel

Product Description

The VLIER BMH12A is a threaded ball plunger designed for applications requiring controlled end force in a compact, lightweight form. The body threads at M12 x 1.75 and measures 0.866 inches in body length. The steel ball has a diameter of 0.315 inches and a maximum ball reach of 0.098 inches. Initial end force is rated at 16.86 pounds, with a final end force of 25.85 pounds. Both the body and ball are constructed from steel for durability in industrial positioning and indexing applications. Licensed trades and mechanical assembly technicians install this type of component in fixtures, jigs, and automated equipment.

This ball plunger is suited for light-duty positioning, detenting, and indexing tasks where a repeatable spring-loaded force is required. The M12 x 1.75 thread allows installation into standard metric-threaded bores. Its compact body length and controlled force range make it appropriate for use in machine tools, fixture plates, assembly jigs, and similar mechanical assemblies in manufacturing and industrial environments. The purple color code aids in identification and sorting among multiple plunger variants in a toolroom or maintenance setting.

Compatibility

Designed as an OEM-style replacement or direct-fit component for applications requiring an M12 x 1.75 threaded ball plunger with controlled spring-loaded end force in industrial and mechanical assembly equipment.

Installation Notes

Installation is performed by mechanical technicians or maintenance personnel using standard metric hand tools. Ensure the receiving bore is properly tapped to M12 x 1.75 before installation. De-energize and lock out any machinery before installing or removing the plunger. Do not exceed the rated ball reach or apply side-loading forces beyond the plunger design limits.
