Vlier B62N Threaded Ball Plunger 5/8-11 Steel Locking

Product Description

The VLIER B62N is a threaded ball plunger designed for controlled end-force applications where precise, repeatable positioning or detenting is required. It features a 5/8-11 thread, a 0.375-inch steel ball diameter, and a 0.984-inch body length. The B62N delivers an initial end force of 9 pounds and a final end force of 18 pounds, providing a defined force range suited to indexing fixtures, jigs, and positioning mechanisms. A locking element is included to secure the plunger in the threaded bore and prevent back-out under vibration or repeated cycling. As one of the smallest and lightest spring-loaded devices in its class, it fits where space is limited.

The B62N is used in industrial, tooling, and machine assembly applications where a compact, threaded spring plunger must hold or index a moving component at a set position. Typical installations include fixture plates, slides, rotary tables, and automated assembly equipment. The maximum ball reach of 0.096 inches is suited to shallow detent grooves or light-engagement indexing. Both the body and ball are steel construction, making this plunger appropriate for environments with moderate wear demands and mechanical loading.

Key Features

• 5/8-11 threaded body for direct installation into tapped holes
• Steel body and steel ball for durability in mechanical positioning applications
• Initial end force of 9 pounds, final end force of 18 pounds for controlled detent engagement
• Maximum ball reach of 0.096 inches suited to shallow-groove indexing
• Integrated locking element prevents back-out under vibration or repeated use
• Compact, lightweight form factor for space-constrained installations

Compatibility

Designed as an OEM-style replacement or direct-install threaded ball plunger for applications requiring a 5/8-11 thread and controlled spring end force in indexing and positioning assemblies.

Installation Notes

Install using a standard wrench on the body hex into a clean, properly tapped 5/8-11 threaded hole. Ensure the mating detent groove depth is compatible with the 0.096-inch maximum ball reach before installation. The locking element should be engaged to the specified torque per the machine designer's requirements to prevent loosening during operation. De-energize or lock out any powered equipment before servicing plungers installed in automated machinery.
