Mitutoyo 614167-531 Square Steel Gage Block 0.127 in Grade 0

Product Description

The MITUTOYO 614167-531 is a square steel gage block measuring 0.127 inches, manufactured to Grade 0 accuracy standards per ASME specifications. Gage blocks are precision-ground reference standards used to calibrate measuring instruments, set comparators, and verify dimensional tolerances on the shop floor or in a metrology lab. This block includes a Certificate of Inspection, confirming it has been individually measured and documented at the Grade 0 tolerance level. Grade 0 blocks are suited for high-accuracy calibration and inspection work where tighter tolerances are required compared to Grade AS-1 and Grade AS-2 blocks.

This gage block is intended for use in metrology labs, tool rooms, and quality control environments. It is appropriate for calibrating micrometers, calipers, height gages, and other precision measuring instruments. Machinists, quality technicians, and metrologists performing dimensional inspection in manufacturing settings are the primary users. It is supplied individually and is compatible with standard gage block wringing and storage practices.

Key Features

• Grade 0 accuracy per ASME standards for high-precision calibration use
• 0.127-inch nominal size, precision-ground steel construction
• Includes Certificate of Inspection documenting individual measurement verification
• Square block geometry compatible with standard gage block accessories and holders
• Steel material provides durability and stability under normal metrology lab conditions

Compatibility

Designed as an OEM-style precision reference standard compatible with standard gage block wringing sets and accessories used in ASME-compliant metrology and dimensional inspection applications.

Installation Notes

Gage blocks are handled by calibration technicians and quality control professionals. Clean block surfaces thoroughly before wringing or use to prevent contamination that can affect accuracy. Store in a protective case away from humidity and temperature extremes to maintain dimensional stability. Follow ASME B89.1.9 handling and care guidelines for precision gage blocks.
