Vlier DSBMH8 Threaded Ball Plunger M8 X 1.25

Product Description

The VLIER DSBMH8 is a threaded ball plunger designed for controlled end-force applications in industrial and mechanical assemblies. It features a stainless steel body with an M8 x 1.25 thread and a nylon ball measuring 0.196 inches in diameter. The body length is 0.63 inches with a maximum ball reach of 0.059 inches. Initial end force is rated at 9 pounds and final end force at 13.49 pounds, providing consistent, repeatable positioning force. This plunger is installed by machinists, maintenance technicians, and mechanical assemblers in jigs, fixtures, and precision tooling where controlled detent force is required.

The DSBMH8 is suited for light-duty controlled-force positioning tasks in manufacturing and assembly environments. Its nylon ball minimizes surface marring on workpieces and mating components, making it appropriate for use in fixture bodies, tooling plates, and positioning systems where metal-on-metal contact is undesirable. The M8 x 1.25 thread is a standard metric size found across a wide range of machined components and assemblies. The purple color code identifies the specific force rating within the VLIER product line for quick visual identification during installation and maintenance.

Key Features

• M8 x 1.25 thread pitch for standard metric fitment
• Stainless steel body for corrosion resistance in shop and industrial environments
• Nylon ball reduces surface marring on mating components
• Controlled end force: 9 pounds initial, 13.49 pounds final
• Compact body length of 0.63 inches suits space-constrained assemblies
• Purple color code for quick force-rating identification

Compatibility

Designed as a direct-install threaded ball plunger for M8 x 1.25 tapped holes in jigs, fixtures, tooling plates, and mechanical assemblies requiring controlled detent or positioning force.

Installation Notes

Installation is performed by machinists or mechanical assemblers using a standard hex wrench or spanner suited to the M8 body. Always ensure the mating tapped hole is clean and correctly threaded before installation. Do not overtighten the body, as this can affect ball travel and end-force performance. No special codes govern installation of mechanical plungers, but follow the equipment manufacturer's torque and assembly guidelines for the host component.
