Spi CMS160622053 Outside Micrometer 11 in Range

Product Description

The SPI CMS160622053 is a mechanical outside micrometer designed for high-precision linear measurement in machining, tooling, and metrology applications. It covers a measurement range of 11 inches with a graduation of 0.0001 inches and an accuracy of 0.0003 inches, making it suitable for close-tolerance inspection work. The measuring faces are solid carbide for durability and wear resistance. The thimble uses a ratchet stop mechanism to deliver consistent measuring pressure and repeatable readings. This instrument comes factory calibrated with NIST traceability certification, case, and a short form certificate of calibration included. Machinists, quality technicians, and tool room professionals install and use this micrometer in precision measurement workflows.

This micrometer is used in machine shops, manufacturing facilities, and quality control environments where large-diameter or long-span outside dimensions must be verified to tight tolerances. The 11-inch range accommodates large workpieces that fall outside the capacity of standard bench-top instruments. Its satin chrome finish reduces glare during use and resists corrosion in shop environments. The rotating spindle and ratchet stop thimble support consistent technique across repeated measurements.

Key Features

• Satin chrome finish reduces glare and resists corrosion

Compatibility

Designed as a general-purpose mechanical outside micrometer suitable for large-range precision measurement tasks in machining, quality control, and tool room environments.

Installation Notes

This instrument is used by machinists and metrology technicians and requires no installation in the traditional sense. Before use, verify calibration status using the included certificate and check the zero setting at the appropriate standard. Store the micrometer in its protective case when not in use to preserve measuring face integrity and calibration. Do not overtighten the thimble or use the spindle lock to force the instrument onto a workpiece.
