Spi CMS160726138 Screw Thread Micrometer 0-1 in

Product Description

The SPI CMS160726138 is a mechanical screw thread micrometer designed for precision thread measurement in the 0 to 1 inch range. It features a ratchet stop thimble for consistent measuring pressure and delivers a graduation of 0.001 inches with an accuracy of plus or minus 0.0002 inches. The tool is NIST traceable and ships with a short-form certificate of calibration and a protective case. Interchangeable anvils allow the micrometer to be configured for different thread forms and pitches, though anvils are not included with this unit. It is intended for use by machinists, quality control technicians, and precision measurement professionals.

This micrometer is suited for shop floor and inspection applications where screw thread geometry must be verified to tight tolerances. The mechanical operation requires no batteries or data output connections, making it a reliable choice for environments where electronic instruments are impractical. The 0 to 1 inch measurement range covers a wide variety of common fastener and threaded component sizes encountered in manufacturing, tooling, and maintenance work.

Key Features

• 0 to 1 inch measurement range with 0.001 inch graduation
• Accuracy of plus or minus 0.0002 inches
• Ratchet stop thimble for repeatable measuring force
• Interchangeable anvil design for multi-thread-form use (anvils not included)
• NIST traceable calibration with short-form certificate included
• Includes protective carrying case

Compatibility

Designed as a stand-alone screw thread micrometer body accepting interchangeable anvils; compatible anvil sets are sold separately. No specific model or system compatibility was provided in the product data.

Installation Notes

This instrument is handled and serviced by metrology technicians or trained machinists. Before use, verify calibration status against the included certificate and clean measuring faces with a lint-free cloth. Do not apply excessive force beyond what the ratchet stop allows, as this can affect accuracy and damage the spindle. Store in the included case when not in use to protect the measuring surfaces.
