Vlier NS52 Threaded Spring Plunger 10-32 3/4in Steel

Product Description

The VLIER NS52 is a threaded spring plunger designed for indexing, positioning, and light-duty holding applications in mechanical assemblies. The plunger features a 10-32 thread size with a 3/4 inch thread length and a 1/8 inch projection. The steel body provides durability in industrial and OEM settings. With an initial end force of 2.9 pounds and a final end force of 11.1 pounds, the NS52 delivers consistent spring tension across its travel range. The phenolic nose reduces friction and prevents marring on contact surfaces. Machinists, maintenance technicians, and OEM assembly professionals typically install these plungers in tooling, fixtures, and production equipment.

The NS52 is suited for use in precision tooling, jigs, fixtures, and mechanical assemblies where repeatable part positioning is required. The standard plunger length type makes it a straightforward drop-in for new builds or replacement installs in light industrial and manufacturing environments. Its compact form factor allows installation in tight threaded bores without special clearance requirements. No locking element is included, making it appropriate for applications where removal or adjustment of the plunger is anticipated during service.

Key Features

• 10-32 thread size with 3/4 inch thread length for standard tapped-hole installation
• 1/8 inch plunger projection provides controlled engagement depth
• Steel body construction for durability in industrial service
• Phenolic nose material minimizes surface marring on mating components
• 2.9 pound initial end force and 11.1 pound final end force for consistent spring-loaded positioning
• No locking element - field-adjustable and removable without special tooling

Compatibility

Designed as an OEM-style replacement or new-install spring plunger for mechanical assemblies, fixtures, and tooling applications requiring a 10-32 threaded plunger with standard projection.

Installation Notes

Installation is performed by machining or OEM assembly technicians using a standard hex wrench or driver suited to the plunger body. The mating component should be de-energized or secured before plunger installation to prevent unintended movement. Do not overtighten, as thread damage will affect spring force and plunger travel. Verify bore thread condition before installation to ensure proper engagement.
