Vlier S62N Threaded Spring Plunger 5/8-11 Steel Locking

Product Description

The VLIER S62N is a threaded spring plunger designed for positive positioning, indexing, and light-duty locking applications in mechanical assemblies. It features a 5/8-11 thread with a 1-1/2 inch thread length and a standard-length steel body. The plunger nose diameter ranges from 0.308 to 0.310 inches with a 5/16 inch projection. Initial end force is 10.5 pounds and final end force is 25.5 pounds, making it suited for applications that require controlled resistance during actuation. A built-in locking element holds the plunger in place against rotation or back-out after installation. Machinists, tool and die makers, and mechanical assemblers typically install this component.

The S62N is used in fixtures, jigs, machine tool components, and production tooling where repeatable detent or indexing action is required. The 5/8-11 thread allows installation into standard tapped holes in steel or aluminum workpieces. The locking element eliminates the need for secondary thread-locking compounds in most applications, simplifying assembly and service. This plunger is appropriate for both light-production and precision-tooling environments where consistent spring force and plunger return are critical to part performance.

Key Features

• 5/8-11 thread with 1-1/2 inch thread and body length for deep engagement in workpieces
• 10.5 lb initial end force and 25.5 lb final end force for controlled detent resistance
• Plunger projection of 5/16 inch for reliable contact with mating components
• Steel body and steel nose material for durability in industrial tooling environments
• Integrated locking element prevents back-out without additional thread-locking agents
• Standard plunger length type for straightforward fitment in common tapped-hole configurations

Compatibility

Designed as an OEM-style threaded spring plunger for standard 5/8-11 tapped holes in fixtures, jigs, and mechanical tooling assemblies.

Installation Notes

Install using a hex wrench or spanner into a clean, properly tapped 5/8-11 hole. Ensure the mating surface and thread are free of debris before threading in the plunger. The locking element engages as the plunger is torqued into position - do not overtighten, as this can damage the locking feature or distort the plunger body. Disengage any spring-loaded or indexing mechanism before removal to avoid uncontrolled plunger ejection.
