Mitutoyo 167-146 Flat End Micrometer Standard 6 in

Product Description

The MITUTOYO 167-146 is a flat end micrometer calibration standard designed to verify and maintain the accuracy of outside micrometers. The reference bar measures 6 inches in length and is calibrated to an accuracy of 0.000150 inches, making it suitable for precision measurement workflows in machine shops, calibration labs, and trade environments where tight tolerances are critical. A heat insulating handle is included to prevent thermal expansion from body heat affecting the reference length during use. This standard is supplied pre-calibrated and ready for immediate service use.

This calibration standard is used in any setting that requires periodic verification of outside micrometer accuracy, including manufacturing facilities, toolrooms, and field service operations. Metrology technicians and precision instrument calibration professionals use reference standards like the 167-146 to confirm micrometer spindle and anvil alignment and to satisfy inspection recordkeeping requirements. The 6-inch length covers a range commonly needed for verifying larger-capacity outside micrometers.

• Accuracy of 0.000150 inches for high-precision calibration verification
• Includes heat insulating handle to minimize thermal error during measurement
• Supplied calibrated and ready for immediate use
• UNSPSC Code 41111600 for streamlined procurement classification

Compatibility

Designed for use with outside micrometers requiring a 6-inch flat end calibration reference standard.

Installation Notes

This is a calibration reference standard, not an installed component. Always handle the standard using the included heat insulating handle to prevent body heat from altering the reference length. Store the standard in its protective case when not in use to avoid surface damage to the flat ends. Calibration procedures should be performed by qualified metrology personnel in accordance with applicable measurement assurance standards.
