Spi CMS220519013 Electronic Screw Thread Micrometer

Product Description

The SPI CMS220519013 is an electronic screw thread micrometer designed to measure the pitch diameter of threaded fasteners and similar workpieces with high repeatability. It covers a measurement range of 1 to 2 inches with a resolution of 0.0001 inches, making it suitable for close-tolerance inspection work in manufacturing, machining, and quality control environments. The micrometer features a ratchet thimble for consistent measuring pressure, a digital counter for direct readout, and a data output port for connection to statistical process control systems or data loggers. Licensed machinists, metrology technicians, and quality inspectors are the primary users of this instrument.

This micrometer is built for shop floor and inspection room use where threaded part verification is required. The 1 to 2 inch range covers a wide variety of common fastener and threaded component diameters encountered in precision manufacturing. The interchangeable anvil system allows the same instrument body to be adapted to different thread forms. It arrives calibrated and is compliant with ASME 89.1.13 standards, which is a common requirement for documented inspection processes in aerospace, automotive, and general industrial applications.

Key Features

• Electronic operation with digital counter for direct readout without interpolation
• Measurement range of 1 to 2 inches with 0.0001 inch graduation
• Ratchet thimble delivers consistent, repeatable measuring force
• Data output port supports SPC and external data logging integration
• Interchangeable stainless steel anvils adapt the tool to different thread forms
• Positive lock nut secures the spindle at a set measurement
• Arrives factory calibrated to ASME 89.1.13 standards

Compatibility

Designed for use in precision thread inspection applications requiring a 1 to 2 inch electronic screw thread micrometer with interchangeable anvils and ASME 89.1.13 compliance.

Installation Notes

This is a precision measuring instrument, not an installed component. Handle with care and store in the included plastic box when not in use to protect the anvils and spindle from damage. Before use, verify calibration with a known standard and clean all measuring surfaces. Avoid dropping or placing the instrument on surfaces where it may contact cutting fluids or abrasive debris.
