Spi CMS160622012 Outside Micrometer Set 3 Piece 0-3 in

Product Description

The SPI CMS160622012 is a 3-piece mechanical outside micrometer set covering a measurement range of 0 to 3 inches. Each micrometer features a ratchet stop thimble that delivers consistent, repeatable seating force, reducing operator-to-operator variation in readings. The set holds an accuracy of 0.0001 to 0.0002 inches and ships calibrated with NIST traceability certification included. These tools are intended for machinists, precision fabricators, and mechanical technicians who require reliable dimensional measurement in shop or field environments.

This set is well suited for general precision measurement tasks in manufacturing, machining, HVAC equipment fabrication, and mechanical service applications. The 3-piece configuration covers 0 to 1 inch, 1 to 2 inches, and 2 to 3 inches, giving the technician full coverage across the range without changing tools. An enamel finish provides corrosion resistance in typical shop conditions. The rotating spindle design allows smooth, consistent advancement during measurement.

• Accuracy of 0.0001 to 0.0002 inches per reading
• NIST traceability certification included out of the box
• Rotating spindle for smooth, controlled spindle advancement
• Enamel finish for durability in shop environments

Compatibility

Designed as a general-purpose outside micrometer set suitable for standard inch-based dimensional measurement tasks across machining, fabrication, and mechanical service applications.

Installation Notes

Outside micrometers are precision instruments and should be handled, stored, and used by qualified machinists or technicians familiar with proper micrometer technique. Store in the provided case when not in use to protect calibration. Clean measuring faces before use and verify the zero reading at each range before taking measurements. Do not overtighten the spindle against the workpiece; use the ratchet stop to apply correct measuring force.
