Mitutoyo 167-147 Micrometer Setting Standard Bar 7 Inch

The Mitutoyo 167-147 is a precision setting standard bar designed for the zero point calibration and accuracy verification of outside micrometers. This 7-inch standard provides a stable reference length for ensuring micrometer measurements remain accurate and reliable.

Key Features:

• 7-inch nominal length for calibrating micrometers in the 6-7 inch range
• 0.31-inch diameter bar provides comfortable handling and stable contact
• Flat and precision-lapped measuring faces ensure accurate zero point setting
• Heat-insulating handle prevents thermal expansion from body heat during handling
• Hardened and stabilized steel construction for long-term dimensional stability

Micrometer setting standards are essential calibration tools for maintaining measurement accuracy in precision machining, quality control, and inspection applications. The insulated handle design minimizes thermal transfer, ensuring the standard maintains its calibrated length during use.
