Mitutoyo 167-152 Micrometer Standard Bar 12 Inch Calibration Tool

The Mitutoyo 167-152 is a precision 12-inch micrometer standard bar designed for accurate calibration and zero-point setting of outside micrometers. This essential measurement tool ensures your micrometers maintain accuracy across their full range of measurement.

Key Features:

• 12-inch (304.8mm) length for calibrating large-capacity micrometers
• 0.37-inch diameter hardened steel bar
• Flat and lapped measuring faces for precise contact and accuracy
• Heat insulating handle prevents thermal expansion from body heat transfer
• Manufactured to strict Mitutoyo tolerances for reliable calibration standards
• Ideal for quality control labs, machine shops, and inspection departments

Micrometer standard bars are critical tools for maintaining measurement accuracy. The heat-insulated handle design minimizes dimensional changes caused by handling, while the precision-lapped measuring surfaces provide a stable reference for zero-point calibration. This 12-inch length is commonly used for verifying 11-12 inch outside micrometers.
