Mitutoyo 614115-531 Square Steel Gage Block 0.15in Grade 0

Product Description

The MITUTOYO 614115-531 is a square steel gage block measuring 0.15 inches in overall length, manufactured to Accuracy Grade 0 tolerances. Gage blocks are precision reference standards used to calibrate measuring instruments, set up comparators, and verify dimensional tolerances in metrology and machining environments. This block ships with a Certificate of Inspection, confirming it has been measured and documented to Grade 0 accuracy requirements per ASME standards. Calibration technicians, machinists, and quality control personnel use blocks like this as part of structured gage sets or as individual slip-block references in high-precision measurement workflows.

This gage block is suited for use in tool rooms, quality labs, and precision machining shops where dimensional verification demands Grade 0 accuracy. It is appropriate for both standalone measurements and use within a larger gage block stack. The included Certificate of Inspection supports traceability requirements common in ISO and ASME-compliant quality systems. Applications include instrument calibration, surface plate setup, and fixed-reference comparator work in both light industrial and precision manufacturing environments.

Key Features

• Grade 0 accuracy meets stringent dimensional tolerance requirements per ASME standards
• Square steel construction provides durability and resistance to wear during repeated use
• 0.15-inch nominal size for close-tolerance reference and stacking applications
• Includes Certificate of Inspection for documented traceability
• Individually packaged, sold as a single block

Compatibility

Designed as an OEM-style precision reference standard compatible with standard gage block sets and comparator setups requiring ASME-conforming Grade 0 square steel blocks.

Installation Notes

Gage blocks are handled by calibration technicians and precision machinists familiar with slip-block technique. Always clean and deburr mating surfaces before wringing blocks together to prevent damage to lapped faces. Store in the supplied case away from temperature extremes to maintain dimensional stability. Follow ASME B89.1.9 handling and storage guidelines for gage block care.
