Vlier BL62 Threaded Ball Plunger 5/8-11 Steel

Product Description

The VLIER BL62 is a threaded ball plunger designed to provide controlled end force in precision mechanical assemblies. It features a 5/8-11 thread, a 0.375 inch steel ball diameter, and a body length of 0.984 inches. The spring-loaded steel ball delivers an initial end force of 4.5 pounds and a final end force of 9 pounds, with a maximum ball reach of 0.096 inches. Marketed as one of the smallest and lightest spring-loaded devices in its class, the BL62 is suited for applications where consistent, repeatable positioning force is required without adding bulk to the assembly.

The BL62 is used in tooling fixtures, jigs, indexing mechanisms, and light-duty positioning applications across manufacturing and industrial maintenance environments. Its compact threaded body allows installation in tight spaces where standard plungers would not fit. The controlled end force makes it appropriate for applications requiring a predictable detent or stop without damaging mating surfaces.

Key Features

• 5/8-11 threaded body for direct installation into tapped holes
• 0.375 inch steel ball with 0.096 inch maximum reach
• 4.5 pound initial end force and 9 pound final end force for controlled positioning
• Steel body and steel ball construction for durability in industrial use
• No locking element - simple, direct installation without thread-locking hardware
• Compact design - one of the smallest and lightest spring-loaded plunger configurations available

Compatibility

Designed as an OEM-style replacement or direct-install threaded ball plunger for tooling fixtures, jigs, and indexing assemblies requiring a 5/8-11 threaded mounting interface.

Installation Notes

Installation requires a properly tapped 5/8-11 threaded hole in the mating component. De-energize or lock out any moving machinery before installing or servicing plungers in active fixtures or automated equipment. Use appropriate thread engagement depth to ensure full spring travel and avoid bottoming the ball. Do not overtighten, as excess torque can distort the body and affect spring force consistency.
