Vlier S52 Threaded Spring Plunger 10-32 Steel

Product Description

The VLIER S52 is a standard threaded spring plunger designed for indexing, positioning, and light-duty ball-detent applications in mechanical assemblies. The plunger features a 10-32 thread with a 3/4-inch thread length and a 1/8-inch nose projection. The steel body and steel nose provide durability in metal-to-metal contact environments. Initial end force is 2.9 pounds and final end force is 11.1 pounds, making the S52 well suited for applications requiring firm, repeatable engagement without heavy actuation force. Machinists, maintenance technicians, and assembly professionals install this type of component in jigs, fixtures, panels, and tooling.

The S52 is typically installed in tapped 10-32 holes in metal panels, machined blocks, or fixture plates where controlled spring-loaded engagement is needed. Common applications include detent positioning in sliding or rotating assemblies, panel latching, and component registration in production tooling. The standard plunger length type and fixed projection keep installation straightforward in both OEM and field-service scenarios.

Key Features

• 10-32 threaded body with 3/4-inch thread length for direct installation into tapped holes
• 1/8-inch plunger nose projection provides controlled engagement depth
• 2.9 pound initial end force and 11.1 pound final end force for firm detent action
• Steel body and steel nose for metal-contact durability
• Standard plunger length type with no locking element for straightforward torque adjustment
• Compact design suits tight-clearance fixture and panel installations

Compatibility

Designed as an OEM-style replacement or direct-install spring plunger for any assembly requiring a 10-32 threaded spring plunger with a 3/4-inch thread length and 1/8-inch nose projection.

Installation Notes

Install into a clean, properly tapped 10-32 through or blind hole using a hex key or appropriate drive tool. Ensure the mating hole depth accommodates the full 3/4-inch thread length without bottoming out the plunger body. Disengage or de-energize any moving assembly before installation or removal to avoid unintended actuation. No locking element is present, so apply thread-locking compound if vibration resistance is required per the assembly specification.
