Spi CMS160622050 Outside Micrometer Set 12 Pc 12 in

Product Description

The SPI CMS160622050 is a 12-piece mechanical outside micrometer set designed for precision linear measurement in machine shops, manufacturing facilities, and skilled-trade environments. The set covers measurements up to 12 inches with an accuracy of 0.0001 to 0.0002 inches, making it suitable for close-tolerance work in metalworking, fabrication, and maintenance applications. Each micrometer features a ratchet stop thimble for consistent measuring force and a rotating spindle. All micrometers are factory calibrated and finished in enamel for durability. This set is intended for machinists, toolmakers, and precision measurement technicians.

This set is appropriate for use in production machining, quality control, and maintenance inspection across a range of industrial and trade settings. It is well suited for shops that require coverage across a full inch-range spread without purchasing individual micrometers. The 12-piece configuration provides a complete range from small-diameter work up to 12-inch measurements, making it a practical bench-side or toolroom set. No digital counter is included, keeping operation straightforward for technicians who prefer analog readout instruments.

Key Features

• 12-piece set covering measurements up to 12 inches
• Accuracy of 0.0001 to 0.0002 inches for close-tolerance applications
• Ratchet stop thimble provides repeatable, consistent measuring force
• Rotating spindle design for smooth operation
• Factory calibrated and ready for immediate use
• Enamel finish for corrosion resistance and durability

Compatibility

Designed as a general-purpose outside micrometer set for standard inch-measurement applications in machine shop, quality control, and industrial maintenance environments.

Installation Notes

Outside micrometers should be handled and stored by qualified machinists or precision measurement technicians. Store each micrometer in its designated case slot to prevent contact damage to measuring faces and spindle threads. Before use, verify calibration with the included standards and clean all measuring surfaces with a lint-free cloth. Never force the spindle against a workpiece; use the ratchet stop to apply controlled, consistent measuring pressure.
