Spi Z2999 Cmm Styli Wrench M2 Thread

Product Description

The SPI Z2999 is a CMM styli wrench designed for use with CMM touch trigger probes. This small, purpose-built hand tool provides the grip and torque control needed to properly seat or remove M2-threaded styli without damaging delicate probe threads. Correct installation and removal torque is critical in coordinate measuring machine work, where thread damage or improper stylus seating directly affects measurement accuracy. The Z2999 is used by metrology technicians and quality control professionals who service and maintain CMM probe assemblies.

This wrench is suited for use in metrology labs, manufacturing quality departments, and calibration facilities where CMM touch trigger probes are regularly serviced. The M2 thread specification matches the standard thread used on many CMM styli configurations. It is a bench-use accessory kept at the CMM station for routine stylus changes and probe maintenance tasks.

Key Features

• Designed specifically for M2-threaded CMM styli installation and removal
• Compatible with CMM touch trigger probe assemblies
• Provides controlled grip to avoid over-torquing or cross-threading delicate M2 threads
• Compact form factor suited for bench-side use at CMM workstations

Compatibility

Designed for use with CMM touch trigger probes requiring M2-threaded styli. No specific model compatibility data was provided by the manufacturer for this listing.

Installation Notes

This wrench is used by metrology technicians during routine stylus changes on CMM touch trigger probes. Before changing styli, power down or pause the CMM and follow the probe manufacturer guidelines for proper seating torque on M2 threads. Avoid applying excessive force, as over-torquing M2 threads can damage the stylus or probe body and compromise measurement repeatability.
