Vlier SBMH8N Threaded Ball Plunger M8 X 1.25 Ss

Product Description

The VLIER SBMH8N is a threaded ball plunger designed for indexing, positioning, and light-duty detent applications in precision assemblies. It features a stainless steel body and stainless steel ball, making it suitable for environments where corrosion resistance is required. The M8 x 1.25 thread allows for direct installation into a tapped hole. The ball diameter measures 0.196 inches with a maximum ball reach of 0.059 inches. Initial end force is 9 pounds and final end force is 13.49 pounds. A built-in locking element secures the plunger in place after adjustment. Machinists, tool and die technicians, and mechanical assembly professionals typically install this component.

This ball plunger is suited for use in jigs, fixtures, machine tooling, and light mechanical assemblies where repeatable positioning or tactile detent feedback is needed. The stainless steel construction makes it appropriate for cleanroom, food-grade-adjacent, or corrosion-prone environments. Its compact body length of 0.63 inches fits space-constrained assemblies. The color code for this variant is purple, which aids in field identification when multiple spring-force variants are in use.

Key Features

• M8 x 1.25 thread for direct installation into a standard tapped hole
• Stainless steel body and stainless steel ball for corrosion resistance
• 9 pound initial end force and 13.49 pound final end force for controlled detent action
• Maximum ball reach of 0.059 inches for precise engagement depth
• Integrated locking element prevents plunger from backing out after installation
• Purple color code for quick identification among multiple spring-force options

Compatibility

Designed as a direct-install threaded ball plunger for any application with an M8 x 1.25 tapped hole requiring spring-loaded ball detent or positioning functionality.

Installation Notes

Install using a standard hex wrench or spanner appropriate for the M8 body. Ensure the mating tapped hole is clean and free of debris before threading in the plunger. The locking element should be engaged after positioning to prevent loosening under vibration or repeated cycling. De-energize or lock out any powered equipment before servicing assemblies that contain this component.
