Vlier SSS60 Threaded Spring Plunger 1/2-13 Stainless Steel

Product Description

The VLIER SSS60 is a threaded spring plunger designed for indexing, positioning, and light-duty detent applications in industrial and mechanical assemblies. The body and nose are both machined from stainless steel, making this plunger suitable for corrosive or wash-down environments. It features a 1/2-13 thread with a standard 1-1/4 inch thread length and a 1/4 inch projection. Initial end force is 6.6 pounds and final end force is 17.4 pounds. This plunger is installed directly into a threaded hole in a fixture, jig, die, or machine component and requires no locking element.

The SSS60 is used in manufacturing fixtures, tooling plates, assembly jigs, and similar mechanical setups where repeatable positioning or light detent action is needed. Its stainless steel construction makes it a fit for food processing equipment, medical device fixtures, and other applications where corrosion resistance is a requirement. The standard plunger length type suits most general-purpose industrial mounting configurations. Machinists, tool and die makers, and maintenance technicians are the typical installers.

Key Features

• Stainless steel body and nose for corrosion resistance in harsh or wash-down environments
• 1/2-13 thread size with 1-1/4 inch thread length for secure installation in standard tapped holes
• 6.6 lb initial end force and 17.4 lb final end force for consistent, repeatable detent action
• 0.247 to 0.248 inch plunger diameter with 1/4 inch projection
• No locking element - adjustable by thread engagement depth
• Standard plunger length type suits general-purpose fixture and tooling applications

Compatibility

Designed as an OEM-style replacement or direct-install threaded spring plunger for industrial fixtures, tooling plates, jigs, and mechanical assemblies requiring a 1/2-13 threaded body with stainless steel construction.

Installation Notes

Installation requires a properly tapped 1/2-13 hole in the host component. Use an appropriate hex wrench or spanner to thread the plunger body to the desired depth, which sets the effective end force. Power down or de-energize any associated equipment before servicing components in an active assembly. Do not overtighten - this can damage the plunger body or distort the spring mechanism.
