Mitutoyo 167-142 Micrometer Setting Standard Bar 2 Inch

The Mitutoyo 167-142 is a precision 2-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:

• 2-inch nominal length for calibrating micrometers in the 1-2 inch range
• 0.25-inch diameter for easy handling and storage
• 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 like the 167-142 are critical for maintaining measurement accuracy in quality control, inspection, and precision machining applications. The heat-insulating handle is particularly important as it minimizes temperature transfer from your hand, which could cause the steel bar to expand and affect calibration accuracy.
