Spi CMS160714052 Hub Micrometer 0-1 Inch Mechanical

Product Description

The SPI CMS160714052 is a mechanical hub micrometer designed for precision outside measurement in the 0 to 1 inch range. It delivers an accuracy of 0.0001 inches with a matching graduation of 0.0001 inches, making it suitable for close-tolerance work in tool rooms, machine shops, and production environments. The instrument features a ratchet thimble for consistent measuring pressure and a rotating spindle. Both the anvil and spindle are carbide-tipped for wear resistance and long service life. The unit ships calibrated and includes a short form certificate of calibration along with standards documentation and a protective case.

This hub micrometer is used in precision machining, metrology, and quality control applications where tight dimensional tolerances must be verified. It is appropriate for measuring hub features, shafts, and other cylindrical or flat workpieces within its 0 to 1 inch capacity. Machinists, tool and die makers, quality control technicians, and precision measurement specialists are the primary users. The included calibration certificate supports use in ISO-compliant and audited shop environments.

Key Features

• 0 to 1 inch measuring range with 0.0001 inch graduation and 0.0001 inch accuracy
• Ratchet thimble for repeatable, consistent measuring pressure
• Rotating spindle design for ease of adjustment and alignment
• Carbide anvil and carbide spindle for extended wear resistance
• Ships calibrated with a short form certificate of calibration and standards
• Includes a protective case for storage and transport

Compatibility

Designed as a direct-use precision measuring instrument for general outside micrometer applications in the 0 to 1 inch range; compatible with standard micrometer standards sets and calibration fixtures appropriate for that range.

Installation Notes

No installation is required for this measuring instrument. Before use, verify calibration with the included standards and zero the micrometer at the closed position. Keep the spindle and anvil faces clean and free of debris to ensure accurate readings. Store in the provided case when not in use to protect the precision ground surfaces.
