Jergens 30472 Threaded Spring Plunger M6 X 1

Product Description

The JERGENS 30472 is a threaded spring plunger designed for locating, positioning, and indexing applications in workholding and fixturing setups. The body is constructed from steel with a black finish, and the nose is made from Delrin, which provides low-friction contact with workpiece surfaces. The plunger has an M6 x 1 thread size with a 25mm thread length, a maximum plunger diameter of 3.02mm, and a 5mm projection. Initial end force is 1.35 kg and final end force is 5.85 kg. This part is installed without a locking element, making it suited for applications where adjustability is required.

The JERGENS 30472 is used in precision workholding, jig and fixture building, and machine tool setups where repeatable part location is needed. It is threaded directly into a tapped hole in a fixture plate or tooling body. The Delrin nose minimizes marring of finished or soft workpiece surfaces, making this plunger appropriate for use in precision machining, inspection fixtures, and assembly tooling in both production and job-shop environments.

Key Features

• M6 x 1 thread size with 25mm thread length for direct installation into tapped fixture components
• Steel body with black finish for corrosion resistance and durability in shop environments
• Delrin nose reduces wear and prevents marring of workpiece surfaces
• 5mm plunger projection with a 3.02mm maximum plunger diameter for precise locating
• Initial end force of 1.35 kg and final end force of 5.85 kg for consistent spring-loaded positioning
• No locking element, allowing tool-free adjustment and repositioning

Compatibility

Designed as an OEM-style replacement or direct-fit component for threaded spring plunger applications requiring an M6 x 1 threaded body in fixture plates, tooling bodies, and locating assemblies.

Installation Notes

Installation is performed by threading the plunger directly into a properly tapped M6 x 1 hole using a 3mm hex key. Ensure the tapped hole depth and thread engagement are sufficient to fully seat the plunger body before applying load. Verify plunger projection and spring force requirements against the application before final installation. No special tools or certifications are required, but standard machining and fixturing practices should be followed.
