Spi MS160712144 Mechanical Outside Micrometer 2 in

Product Description

The SPI MS160712144 is a mechanical outside micrometer designed for high-precision linear measurement of external dimensions. It covers a measurement range of 2 inches with a graduation of 0.00005 inches and an accuracy of 0.0002 inches, making it suitable for applications where tight tolerances are critical. The measuring faces are made from solid carbide for long-term wear resistance and consistent contact. The tool ships calibrated and includes a short-form certificate of calibration with NIST traceability. It is intended for machinists, tool-and-die workers, quality control technicians, and precision trade professionals who require verified measuring instruments on the job.

This micrometer is suited for precision measurement tasks in manufacturing, machining, metalworking, and quality assurance environments. The rotating spindle design allows for controlled contact force, reducing the risk of measurement error from over-tightening. With a measuring force range of 4.0 to 10.0 N, the tool provides consistent and repeatable readings. It is packaged with a protective case and calibration documentation, making it job-site and shop-ready upon arrival. Appropriate for use in both production floor and inspection room settings where dimensional accuracy is required.

Key Features

• Solid carbide measuring faces resist wear and maintain contact surface integrity over extended use
• Rotating spindle design delivers controlled, repeatable contact pressure
• Calibrated at factory with NIST-traceable short-form certificate of calibration included
• Includes protective case and calibration standards documentation

Compatibility

Designed as a standard outside micrometer for general-purpose external dimensional measurement up to 2 inches in precision machining and inspection applications.

Installation Notes

This instrument should be handled and stored according to standard metrology practices to preserve calibration integrity. Before use, verify the zero setting and clean measuring faces with a lint-free cloth. Avoid dropping or applying side-loading force to the spindle, as this can affect accuracy and alignment. Recalibration should be performed at regular intervals or any time the tool is subjected to impact or temperature extremes.
