Vlier S67N Threaded Spring Plunger 1/8 Thread Steel Locking

Product Description

The VLIER S67N is a standard threaded spring plunger designed for indexing, positioning, and light-duty holding applications in industrial and mechanical assemblies. It features a steel body and steel nose with a 1/8 thread size and a body length of 2-13/32 inches. The plunger diameter ranges from 0.496 to 0.498 inches, with a 1/2 inch projection beyond the mounting surface. An integrated locking element secures the plunger in position after installation, eliminating the need for separate thread-locking compounds. Initial end force is 4 pounds, with a final end force of 31 pounds, making it suitable for applications requiring a firm, positive detent feel.

The S67N is used in tooling fixtures, jigs, machine components, and positioning assemblies where repeatable, spring-loaded engagement is required. It is appropriate for both light manufacturing and precision assembly environments. The locking element makes it well-suited for installations subject to vibration where plunger backing-out could affect function or safety. Installation is typically performed by machinists or mechanical assemblers working with threaded bores sized to accept a 1/8 thread.

Key Features

• Steel body and steel nose construction for durability in industrial environments
• Integrated locking element prevents backing out under vibration
• 1/2 inch plunger projection for positive detent engagement
• 4 pound initial end force and 31 pound final end force for firm positioning feel
• Standard plunger length type for straightforward drop-in replacement
• Plunger diameter range of 0.496 to 0.498 inches for consistent fit

Compatibility

Designed as an OEM-style replacement or direct-fit component for assemblies requiring a 1/8 threaded spring plunger with a standard length profile and locking element.

Installation Notes

Installation is performed by threading the plunger body into a pre-tapped bore of the appropriate thread size using a suitable wrench or installation tool. Power down or de-energize any associated equipment before servicing assemblies containing spring plungers. The locking element engages during installation and should be set to the desired torque position before finalizing. Avoid over-tightening, which can damage the locking element or distort the plunger body.
