Mitutoyo 614123-531 Square Steel Gage Block 0.1003 in Grade 0

Product Description

The MITUTOYO 614123-531 is a square steel gage block ground and lapped to a nominal length of 0.1003 inches at Grade 0 accuracy. Gage blocks serve as precision length references used to calibrate measuring instruments, set comparators, and verify dimensional tolerances in manufacturing and inspection environments. Grade 0 represents a high level of flatness, parallelism, and length accuracy, making this block suitable for tool room calibration and quality lab work. A Certificate of Inspection is included, providing documented traceability for the measurement standard.

This gage block is used in metrology labs, machine shops, and precision manufacturing facilities where dimensional verification and instrument calibration are required. It is appropriate for use with comparator stands, surface plates, and calibration fixtures. Typical end users include quality control technicians, metrology specialists, and toolroom machinists working to ASME standards. The 0.1003-inch size makes it a useful increment for building up gage block stacks to achieve specific reference dimensions.

Key Features

• Grade 0 accuracy per ASME standards for high-precision dimensional reference
• Steel construction provides durability and dimensional stability over repeated use
• Nominal length of 0.1003 inches for precise stack combinations
• Includes Certificate of Inspection for measurement traceability
• Square geometry allows wringing to other gage blocks for stack assemblies

Compatibility

Designed as a standard ASME-compliant gage block for use with comparators, surface plates, and gage block sets requiring a 0.1003-inch reference increment.

Installation Notes

Gage blocks should be handled by metrology or quality control personnel using clean, lint-free gloves to prevent contamination and corrosion. Before use, blocks should be wrung together on a clean surface plate using light pressure and a sliding motion. Store in a temperature-controlled environment and clean with an appropriate gage block cleaning solution after each use to maintain surface condition and dimensional integrity.
