Spi MS160712002 Micrometer Calibration Standard 2 Inch Flat End

Product Description

The SPI MS160712002 is a flat-end micrometer calibration standard used to verify and set the accuracy of outside micrometers. Machined to a maximum length of 2 inches with an accuracy of 0.000080 inches, this gauge rod provides a traceable reference point for calibration tasks on the shop floor or in the field. The part includes a heat insulating handle, which prevents body heat from transferring to the standard and skewing measurements during use. Precision instrument technicians, machinists, and metrology professionals rely on this type of standard to maintain measurement integrity across their tooling inventory.

This calibration standard is suited for use in machine shops, manufacturing facilities, and maintenance environments where micrometer accuracy must be confirmed before critical measurements are taken. It is designed for use with standard outside micrometers and is appropriate for both routine calibration checks and pre-job verification procedures. The flat end configuration provides consistent, repeatable contact with micrometer anvils.

Key Features

• Maximum length of 2 inches for calibrating micrometers in that range
• Accuracy up to 0.000080 inches for high-precision verification
• Flat end shape ensures consistent anvil contact during calibration
• Factory calibrated and ready for immediate use out of the package
• Includes heat insulating handle to prevent thermal expansion errors during handling

Compatibility

Designed for use with outside micrometers that measure in the 2-inch range. No specific brand or model compatibility was stated in the product data.

Installation Notes

This calibration standard is handled by machinists, toolroom technicians, or metrology personnel — not a trade install application. Always hold the standard by the insulating handle to avoid transferring body heat to the gauge body, which can introduce thermal expansion errors. Store in a clean, dry location away from temperature extremes when not in use. Follow your facility's calibration interval procedures and any applicable ISO or ANSI measurement standards when using this standard in a formal calibration program.
