Spi CMS160726119 Screw Micrometer Anvil 4.5-3.5 Tpi

Product Description

The SPI CMS160726119 is a replacement screw micrometer anvil designed for use with SPI Thread Micrometers. This precision anvil features a 60-degree tip geometry matched to standard thread measurement applications, covering a pitch range of 4.5 to 3.5 TPI. Constructed from steel with a bright finish, it provides the dimensional stability and surface integrity required for accurate thread pitch measurement. The anvil accommodates a measurement range of 5.50 mm to 7.00 mm and is sold individually. Licensed metrology technicians, machinists, and quality control professionals use this type of accessory during inspection and verification work.

This anvil is suited for thread measurement tasks in manufacturing, machining, and inspection environments where SPI Thread Micrometers are in use. Its pitch coverage of 4.5 to 3.5 TPI applies to both coarse and moderately fine thread profiles within that range. The 60-degree anvil angle conforms to standard unified and metric thread flank geometry, making it appropriate for routine dimensional inspection on production floors and in calibration labs.

Installation Notes

Installation of micrometer anvils should be performed by a qualified metrologist or machinist familiar with precision measurement instruments. Power down any associated automated measurement systems before handling anvil components. Handle the anvil tip carefully to avoid damage to the 60-degree contact surface, as nicks or burrs will affect measurement accuracy. After installation, verify calibration against a known thread standard before returning the instrument to service.
