Mitutoyo 167-298 Point End Micrometer Calibration Standard

Product Description

The MITUTOYO 167-298 is a point end micrometer calibration standard designed for verifying and calibrating screw thread micrometers. Measuring 5 inches in length with a stated accuracy of 0.00035 inches, this calibration standard provides a reliable reference for confirming micrometer performance in shop or field environments. It includes a heat insulating handle, which prevents thermal expansion from body heat from affecting the measurement reference during use. Calibration technicians and precision machinists rely on standards like this to maintain measurement traceability and instrument accuracy in manufacturing and inspection settings.

This calibration standard is used with screw thread micrometers to verify instrument accuracy before or after critical measurements. It is appropriate for tool rooms, quality control labs, and production floor inspection stations where thread measurement accuracy must be confirmed. The included heat insulating handle makes it practical for extended calibration sessions without introducing measurement error from hand contact.

Key Features

• 5-inch length suits a range of screw thread micrometer verification tasks
• Accuracy of 0.00035 inches supports precise instrument calibration
• Calibrated at the factory for immediate use as a measurement reference
• Includes heat insulating handle to minimize thermal distortion during handling
• Point end geometry compatible with screw thread micrometer anvil configurations

Compatibility

Designed for use with screw thread micrometers requiring a point end calibration standard reference.

Installation Notes

This calibration standard should be handled using the included heat insulating handle to avoid thermal growth from hand contact, which can introduce error into the reference measurement. Allow the standard and the micrometer being calibrated to stabilize at the same ambient temperature before use, following standard metrology practice. Store the standard in its protective case when not in use to prevent damage to the contact surfaces. Calibration work on precision instruments should be performed by qualified technicians following applicable measurement system procedures.
