Vlier SPRSNM16 Pull Ring Plunger M16x2.0 Stainless

Product Description

The VLIER SPRSNM16 is a stainless steel pull ring plunger designed for precise, repeatable indexing and positioning applications. It features an M16x2.0 thread with a 0.56 inch thread length and a non-locking plunger mechanism. The 0.38 inch diameter plunger delivers an initial end force of 1.25 pounds, building to a final end force of 5 pounds, making it suitable for applications that require controlled resistance and positive engagement. The pull ring design allows manual retraction of the plunger without tools, supporting quick-release or adjustable positioning setups in mechanical assemblies.

This plunger is used in industrial and mechanical assemblies where controlled spring-loaded positioning is required. Typical applications include jigs, fixtures, machine tool components, and equipment panels where repeatable stop or index points are needed. The M16x2.0 thread allows installation into standard tapped holes in metal frames, enclosures, or structural members. It is appropriate for both light-duty and moderate-load positioning tasks in manufacturing, automation, and equipment maintenance environments.

Key Features

• Pull ring design allows manual plunger retraction without additional tools
• Non-locking plunger for quick repositioning and repeated engagement
• Stainless steel construction for corrosion resistance in demanding environments
• End force range of 1.25 pounds initial to 5 pounds final for controlled engagement
• M16x2.0 thread for compatibility with standard metric tapped holes
• Compact body length of 1 inch suits space-constrained assemblies

Compatibility

Designed as an OEM-style replacement or direct-install spring plunger for mechanical assemblies requiring an M16x2.0 threaded non-locking pull ring plunger.

Installation Notes

Installation is performed by threading the SPRSNM16 into a properly tapped M16x2.0 hole using a 16mm hex wrench applied to the head. Ensure the mating hole is clean and free of debris before installation. Do not overtighten, as excessive torque may damage the plunger mechanism or the receiving thread. Verify plunger projection and end force requirements against the application before final assembly.
