Spi CMS160622052 Mechanical Outside Micrometer 12 in

Product Description

The SPI CMS160622052 is a mechanical outside micrometer designed for high-precision linear measurement across a 12-inch range. It delivers an accuracy of 0.0003 inches and a graduation of 0.0001 inches, making it suitable for exacting dimensional inspection work in machine shops, tool rooms, and production environments. The micrometer features a ratchet stop thimble for consistent measuring force and a rotating spindle for controlled contact with the workpiece. Measuring faces are solid carbide for extended wear life. The unit ships calibrated with NIST traceability certification included. Machinists, quality technicians, and precision tool professionals are the primary users.

This outside micrometer is used for measuring the outside dimensions of large workpieces where shop-grade accuracy is required. Its 12-inch range covers large-diameter shafts, plates, and stock. The included case, short-form certificate of calibration, and NIST standards documentation make it appropriate for use in quality-controlled environments, aerospace fabrication, heavy industry, and tool and die applications where traceable measurement records are required.

Key Features

• 12-inch maximum measurement range for large-part inspection
• 0.0001-inch graduation for fine, readable resolution
• 0.0003-inch accuracy with NIST traceability certification included
• Ratchet stop thimble ensures repeatable, consistent measuring pressure
• Rotating spindle allows smooth, controlled workpiece contact
• Solid carbide measuring faces resist wear under frequent use
• Hammertone and baked enamel coating/finish on the frame

Compatibility

Designed as an OEM-style precision outside micrometer for use in any application requiring traceable dimensional measurement up to 12 inches on external surfaces.

Installation Notes

This instrument is used by machinists and quality control technicians — no installation in the traditional sense applies. Before use, verify the calibration certificate is current and that the anvil and spindle faces are clean and free of debris. Store the micrometer in the included case when not in use to protect the measuring faces and maintain calibration integrity. Do not expose to impact, excessive heat, or corrosive fluids.
