Mitutoyo 167-154 Micrometer Setting Standard Bar 14 Inch

The Mitutoyo 167-154 is a precision 14-inch micrometer setting standard bar designed for accurate zero-point calibration and adjustment of outside micrometers. This essential measurement tool ensures your micrometers maintain accuracy across their measuring range by providing a certified reference length.

Key Features:

• 14-inch length setting standard for large-capacity outside micrometers
• 0.37-inch diameter hardened steel bar for durability and dimensional stability
• Flat and precision-lapped measuring faces ensure accurate contact and repeatability
• Heat-insulating handle prevents thermal expansion from body heat during handling
• Used for zero-point setting and accuracy verification of outside micrometers

Setting standards like the 167-154 are critical tools for maintaining measurement accuracy in precision machining, quality control, and inspection applications. The heat-insulating handle is particularly important when working with measurement tools sensitive to thermal expansion, allowing you to handle the standard without affecting its dimensional accuracy.
