Mitutoyo 614216-531 Square Steel Gage Block 0.65 in Grade 0

Product Description

The MITUTOYO 614216-531 is a square steel gage block with a nominal size of 0.65 inches, manufactured to Grade 0 accuracy. Gage blocks are precision-ground reference standards used to calibrate measuring instruments, set comparators, and verify the accuracy of inspection equipment. This block is supplied with a Certificate of Inspection, confirming that it meets ASME Grade 0 tolerances. Grade 0 blocks are suited for calibration lab environments and precision inspection applications where tight tolerance verification is required. The steel construction provides dimensional stability and resistance to wear under repeated handling by metrologists and quality technicians.

This gage block is intended for use in metrology labs, tool rooms, and quality control departments across manufacturing, machining, and industrial inspection settings. It functions as a calibration reference for micrometers, calipers, height gages, and surface plate setups. Single-block use or wringing into stacks with other gage blocks allows technicians to establish precise reference dimensions for a wide range of measurement tasks.

Key Features

• Grade 0 accuracy per ASME standards, suitable for calibration and high-precision inspection work
• Nominal size of 0.65 inches for direct reference or stacking applications
• Steel construction for dimensional stability and long service life
• Includes Certificate of Inspection for traceability documentation
• Square block geometry compatible with standard wringing and stacking techniques

Compatibility

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

Installation Notes

Gage blocks are handled and stored by metrology or quality control personnel, not field technicians. Clean block surfaces with an appropriate gage block cleaning solution before and after use to prevent corrosion and contamination. When wringing blocks together, apply light pressure and a sliding motion to seat surfaces properly. Store in the supplied case away from temperature extremes to preserve calibration integrity.
