Mitutoyo 611123-531 Steel Gage Block 0.1003 in Grade 0

Product Description

The MITUTOYO 611123-531 is a rectangular steel gage block measuring 0.1003 inches, manufactured to Grade 0 accuracy standards. Gage blocks are precision-ground, dimensionally stable reference standards used to calibrate measuring instruments, set comparators, and verify dimensional tolerances in manufacturing and quality-control environments. This block ships with a Certificate of Inspection, confirming that the measured dimension meets ASME Grade 0 tolerances. Grade 0 blocks are suitable for laboratory and inspection-grade applications where tight dimensional accuracy is required. Machinists, metrologists, and quality technicians are the primary users of individual gage blocks at this accuracy level.

This gage block is used in tool rooms, calibration labs, and inspection departments within industrial and manufacturing facilities. It serves as a reference standard for verifying and calibrating micrometers, calipers, height gages, and comparators. A single 0.1003-inch block is commonly used as part of a wringing stack to achieve a specific target dimension, or on its own as a direct reference for setup and inspection tasks requiring that nominal size.

Key Features

• Grade 0 accuracy per ASME standards, suitable for laboratory and inspection-grade use
• 0.1003-inch nominal dimension, precision-ground steel construction
• Certificate of Inspection included, confirming dimensional conformance
• Rectangular form compatible with standard gage block wring stacking
• Steel material provides durability and dimensional stability under normal calibration-lab conditions

Compatibility

Designed as an individual OEM-style rectangular gage block for use with standard gage block sets and accessories conforming to ASME gage block specifications.

Installation Notes

Gage blocks are handled by metrology technicians and quality-inspection professionals. Before use, clean all mating surfaces thoroughly to prevent contamination that could affect measurement accuracy. Wring blocks together with a smooth sliding and rotating motion rather than pressing faces together forcefully, as improper wringing can damage lapped surfaces. Store in the supplied case away from temperature extremes to maintain dimensional stability.
