Vlier BMH6A Threaded Ball Plunger M6 X 1 Steel

Product Description

The VLIER BMH6A is a threaded ball plunger designed to deliver controlled end force in precision positioning and indexing applications. It features an M6 x 1 thread with a 1 mm pitch, a steel body measuring 0.551 inches in length, and a 0.137 inch diameter steel ball with a maximum ball reach of 0.039 inches. Initial end force is 6.29 pounds and final end force is 9 pounds. As one of the smallest and lightest spring-loaded devices in its class, the BMH6A is suited for applications where space is limited and consistent, repeatable force is required. Machinists, toolmakers, and automation technicians are the typical installers.

The BMH6A is used in jigs, fixtures, tooling plates, and light assembly equipment where a compact, spring-loaded detent or positioning element is needed. Its M6 x 1 threaded body allows installation into standard tapped holes, making it a straightforward drop-in component for new builds or replacements in existing tooling. The controlled end force range of 6.29 to 9 pounds suits applications requiring gentle but positive ball engagement without damaging delicate workpieces or mating surfaces.

Key Features

• M6 x 1 thread with 1 mm pitch for installation in standard metric tapped holes
• Steel body and steel ball for durability in industrial tooling environments
• 0.137 inch (3.50 mm) ball diameter with 0.039 inch (1.00 mm) maximum ball reach
• Initial end force of 6.29 pounds (28 N) and final end force of 9 pounds (40 N)
• Compact form factor - among the smallest and lightest spring-loaded plunger designs available
• Color code: Purple for quick field identification

Compatibility

Designed for use in controlled end force applications requiring a compact spring-loaded detent; fits any component or fixture with a standard M6 x 1 threaded hole.

Installation Notes

Installation requires a properly tapped M6 x 1 hole in the mating component. Use a standard metric hex key or driver appropriate for the plunger body; avoid overtightening, which can distort the thread or restrict ball travel. Ensure the mating bore is clean and free of chips before threading in the plunger. No special tools or certifications are required, but follow any applicable machine safety lockout procedures before servicing tooling or fixtures.
