Vlier S62 Threaded Spring Plunger 5/8-11 Steel

Product Description

The VLIER S62 is a standard threaded spring plunger designed for positioning, locating, and indexing applications in industrial and mechanical assemblies. The steel body accepts a 5/8-11 thread with a 1-1/2 inch thread length, and the steel nose plunger delivers a 5/16 inch projection. Initial end force is 10.5 pounds and final end force is 25.5 pounds, making this plunger suitable for moderate-load indexing and detent work. Machinists, tool and die technicians, and maintenance mechanics install this type of plunger in jigs, fixtures, machine slides, and assembly tooling where repeatable positioning is required.

The S62 is used in light-to-medium duty applications including fixture plates, workholding devices, sliding machine components, and any assembly where a spring-loaded nose must engage a mating recess or detent groove. The standard plunger length type and 5/8-11 thread make it compatible with tapped holes found in common tooling plate and cast iron fixture bodies. No locking element is included, so the plunger can be threaded in and backed out for force adjustment without a secondary locking feature.

Key Features

• 5/8-11 thread size with 1-1/2 inch thread length for secure fixture engagement
• Steel body and steel nose for durability in industrial environments
• 5/16 inch plunger projection for reliable detent and locating action
• 10.5 pound initial end force and 25.5 pound final end force for moderate-load indexing
• Plunger diameter range of 0.308 to 0.310 inches for consistent fit in mating bores
• No locking element, allowing straightforward installation and force adjustment

Compatibility

Designed as a direct-fit replacement or standard installation for tapped 5/8-11 holes in industrial fixtures, jigs, tooling plates, and mechanical assemblies requiring a spring-loaded plunger with standard projection.

Installation Notes

Installation is performed by machinists or maintenance technicians using a standard hex wrench or spanner tool suited to the plunger body. Ensure the mating hole is tapped clean and free of chips before threading in the plunger. De-energize or lock out any machine before servicing or replacing plungers in live assemblies. Because no locking element is present, apply thread-locking compound if vibration is a concern in the application.
