Te-co 53204 Threaded Spring Plunger 10-32 Stainless Steel

Product Description

The TE-CO 53204 is a threaded spring plunger designed for indexing, positioning, and light-duty locking applications in machined assemblies, fixtures, and tooling. It features a 10-32 thread size with a 3/4 inch thread length and a maximum plunger diameter of 0.093 inches. The plunger delivers 2.7 pounds of initial end force and 7.3 pounds of final end force, providing consistent spring tension for repeatable positioning. Both the nose and body are constructed from stainless steel, and a locking element is integrated into the design to secure the plunger at the installed depth. The black finish adds a degree of corrosion resistance alongside the inherent properties of the stainless steel construction.

This spring plunger is suited for use in precision fixturing, jigs, machine tool components, and light assembly equipment where a compact, threaded positioning element is required. The standard plunger length type and small form factor make it appropriate for tight-clearance installations in both manual and semi-automated tooling setups. A 1/16 inch hex drive allows installation and adjustment with standard hex key tooling.

Key Features

• 10-32 thread size with 3/4 inch thread length for easy integration into standard tapped holes
• Stainless steel nose and body construction for durability and corrosion resistance
• Integrated locking element secures plunger position after installation
• 2.7 lb initial end force and 7.3 lb final end force for consistent, repeatable indexing
• 1/8 inch plunger projection (0.125 inches) for controlled engagement depth
• 1/16 inch hex drive for precise torque application during installation
• Black finish applied over stainless steel body

Compatibility

Designed as a standard threaded spring plunger for use in tapped 10-32 holes in fixtures, jigs, tooling plates, and precision machined assemblies requiring light-duty spring-loaded positioning or indexing.

Installation Notes

Installation is performed by threading the plunger into a pre-tapped 10-32 hole using a 1/16 inch hex key. Disengage or de-energize any associated machinery or clamping systems before servicing fixtures that contain spring plungers. The locking element should be engaged after the plunger is set to the desired projection depth to prevent backing out under vibration. Avoid exceeding the rated end force range, as over-compression can damage the internal spring.
