Mitutoyo 167-153 Micrometer Setting Standard Bar 13 Inch

The Mitutoyo 167-153 is a precision micrometer setting standard bar designed for accurate zero point calibration of outside micrometers. This 13-inch standard bar features a 0.37-inch diameter and provides a reliable reference for verifying and adjusting micrometer accuracy.

Key Features:

• 13-inch length for calibrating larger micrometers
• 0.37-inch diameter for comfortable handling and storage
• Flat and lapped measuring faces ensure precise contact and accurate calibration
• Heat insulating handle prevents thermal expansion from body temperature during use
• Hardened and stabilized steel construction for long-term dimensional stability

Mitutoyo setting standards are essential quality control tools for maintaining micrometer accuracy in precision measurement applications. The heat insulating handle is particularly important for maintaining measurement integrity by minimizing thermal transfer from the operator's hand, which could cause expansion and measurement errors.
