Vlier DSBM10N Threaded Ball Plunger M10 X 1.5

Product Description

The VLIER DSBM10N is a threaded ball plunger with an M10 x 1.5 thread size, designed for indexing, positioning, and light detent applications in mechanical assemblies. The body is stainless steel for corrosion resistance, and the ball is nylon, making it suitable for use against softer mating surfaces where metal contact is not acceptable. A built-in locking element secures the plunger in the threaded bore after installation, preventing loosening from vibration. Initial end force is 4.5 pounds and final end force is 7.87 pounds, providing a defined and repeatable detent feel. The body length is 0.748 inches with a maximum ball reach of 0.079 inches.

This plunger is used in jigs, fixtures, tooling, and precision mechanical assemblies across manufacturing, industrial, and trade applications. The M10 x 1.5 thread fits standard metric bores. The nylon ball material is appropriate for applications requiring low friction contact or protection of the mating surface finish. The locking element makes this suitable for installations subject to vibration or repeated cycling where plunger migration is a concern.

Key Features

• M10 x 1.5 thread for standard metric bore fitment
• Stainless steel body for corrosion and wear resistance
• Nylon ball material for soft-contact detent applications
• Built-in locking element prevents loosening under vibration
• 4.5 pound initial end force and 7.87 pound final end force for consistent detent feel
• Compact body length of 0.748 inches with 0.079 inches maximum ball reach

Compatibility

Designed as a standard M10 x 1.5 threaded ball plunger for use in metric-threaded bores in jigs, fixtures, tooling plates, and mechanical assemblies requiring a spring-loaded detent or positioning element.

Installation Notes

Installation is performed by threading the plunger into a prepared M10 x 1.5 tapped bore using a hex key or spanner appropriate for the plunger body. The locking element should be engaged to the specified thread depth to prevent back-out. Ensure the mating bore is clean and free of debris before installation. Power down or de-energize any assembly before servicing plungers in active machinery.
