Mitutoyo 614176-531 Square Steel Gage Block 0.136 in Grade 0

Product Description

The MITUTOYO 614176-531 is a square steel gage block measuring 0.136 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 machining and inspection environments. This block ships with a Certificate of Inspection, confirming it meets ASME dimensional and accuracy standards. Grade 0 indicates a high-accuracy classification suitable for lab and inspection-room use. Metrology technicians, quality control inspectors, and tool-and-die machinists rely on gage blocks like this one to maintain measurement traceability across production and calibration workflows.

This gage block is suited for use in dimensional inspection labs, tool rooms, and quality control departments in both manufacturing and precision machining facilities. Its steel construction provides the durability required for repeated wringing and handling. The 0.136-inch size makes it a useful reference for setups requiring that specific decimal increment. It is typically used individually or as part of a gage block set to build up a target dimension for instrument calibration or workpiece verification.

Key Features

• Grade 0 accuracy classification per ASME standards
• 0.136-inch nominal size, precision-ground steel construction
• Includes Certificate of Inspection for measurement traceability
• Square block geometry supports stable wringing and stacking
• Meets ASME gage block standards for dimensional accuracy

Compatibility

Designed as an OEM-style precision reference standard compatible with general gage block sets and comparator setups requiring a 0.136-inch increment in steel Grade 0 construction.

Installation Notes

Gage blocks should be handled by metrology technicians or quality control personnel trained in proper wringing technique. Store blocks in a controlled environment away from humidity and temperature extremes to prevent corrosion and dimensional drift. Clean contact surfaces thoroughly before wringing to avoid surface damage. Do not use gage blocks as mechanical stops or clamps, as this will damage the lapped surfaces and compromise accuracy.
