Mitutoyo 167-143 Micrometer Setting Standard Bar 3 Inch

The Mitutoyo 167-143 is a precision 3-inch micrometer setting standard bar designed for accurate zero point calibration of outside micrometers. This essential calibration tool ensures your measuring instruments maintain their accuracy over time.

Key Features:

• 3-inch length setting standard for outside micrometers
• 0.25-inch diameter measuring bar
• Flat and precision lapped measuring faces for accurate reference surfaces
• Heat insulating handle prevents thermal expansion from body heat during use
• Hardened and stabilized steel construction for long-term dimensional stability

Setting standards are critical tools for maintaining micrometer accuracy. The heat-insulating handle minimizes measurement errors caused by thermal expansion, while the precision-lapped faces provide a reliable reference surface for calibration. This standard is manufactured to Mitutoyo's exacting quality specifications for use in precision measurement applications.
