Mitutoyo 167-157 Micrometer Setting Standard Bar 17 Inch

The Mitutoyo 167-157 is a precision 17-inch micrometer setting standard bar designed for accurate zero point calibration of outside micrometers. This essential measurement tool ensures your micrometers maintain factory accuracy for critical dimensional inspection work.

Key Features:

• 17-inch length setting standard for large micrometer calibration
• 0.37-inch diameter cylindrical bar design
• Precision flat and lapped measuring faces for accurate reference surfaces
• Heat insulating handle prevents thermal expansion from body temperature
• Used for zero point setting and calibration verification of outside micrometers
• Manufactured to Mitutoyo's strict accuracy standards

This gauge block standard is an indispensable tool for quality control departments, inspection labs, and machine shops that require traceable calibration of precision measuring instruments. The insulated handle allows for comfortable handling while maintaining measurement integrity by minimizing heat transfer from the operator's hand.
