Mitutoyo 614217-531 Square Steel Gage Block 0.75 in Grade 0

Product Description

The MITUTOYO 614217-531 is a square steel gage block measuring 0.75 inches, manufactured to Grade 0 accuracy. Gage blocks are precision-ground reference standards used to calibrate measuring instruments, set up comparators, and verify dimensional tolerances in manufacturing and inspection environments. This block meets ASME standards and includes a Certificate of Inspection, confirming it has been measured and documented at the factory. Grade 0 represents a high level of dimensional accuracy, making it appropriate for tool room and quality control applications where tight tolerances must be verified reliably.

This gage block is suited for use in metrology labs, machine shops, and inspection departments. It serves as a reference standard for calibrating micrometers, dial indicators, height gages, and similar precision instruments. Typical users include quality control technicians, machinists, and metrologists working in both production and tool room settings. The square geometry allows it to be wrung with other gage blocks in a set to build up specific dimensions as needed for a given measurement task.

Key Features

• Grade 0 accuracy per ASME standards for high-precision dimensional reference
• Square steel construction provides durability and long-term dimensional stability
• 0.75 inches nominal size, precise to five decimal places (0.75000 inches)
• Includes Certificate of Inspection for traceability documentation
• Compatible with wringing techniques to combine with other blocks for compound dimensions

Compatibility

Designed as an OEM-style precision reference standard suitable for use with standard gage block accessories and compatible with any ASME-compliant gage block set or holder system.

Installation Notes

Gage blocks are handled by metrology and quality control professionals. Clean the block surfaces with an appropriate solvent and lint-free cloth before and after each use to prevent corrosion and maintain wringing surfaces. Store the block in a temperature-controlled environment away from magnetic fields and vibration. Apply a thin film of oil or approved gage block preservative when storing for extended periods to protect the precision ground surfaces.
