Mitutoyo 614184-531 Square Steel Gage Block 0.144 in Grade 0

Product Description

The MITUTOYO 614184-531 is a square steel gage block measuring 0.144 inches, manufactured to Grade 0 accuracy. Gage blocks are precision reference standards used to calibrate measuring instruments and set comparators to exact dimensional values. This block is made from steel and conforms to ASME standards for dimensional accuracy. It includes a Certificate of Inspection, confirming that the block has been verified to Grade 0 tolerances before leaving the factory. Grade 0 represents a high level of dimensional accuracy, making this block suitable for calibration labs, quality control departments, and precision machining environments where tight tolerances must be verified.

This gage block is used in metrology and quality assurance applications across manufacturing, tooling, and inspection settings. It is appropriate for both shop-floor and lab environments where precise linear measurements must be referenced or instruments must be calibrated to a known standard. Machinists, metrologists, and quality technicians working in aerospace, automotive, and general precision manufacturing routinely use individual gage blocks of this type to build up specific dimensional references or verify instrument accuracy.

Key Features

• Grade 0 accuracy per ASME standards for high-precision dimensional reference
• Steel construction for durability and dimensional stability
• 0.144-inch nominal size for precise linear reference or gauge stack builds
• Includes Certificate of Inspection confirming factory-verified accuracy
• Square block form for stable wringing and stacking with other gage blocks

Compatibility

Designed as an OEM-style precision reference standard compatible with standard gage block sets and accessories conforming to ASME B89.1.9 or equivalent metrology standards. Suitable for use with gage block holders, comparator stands, and wringing fixtures that accept square-form gage blocks.

Installation Notes

Gage blocks are handled and set by metrologists, quality technicians, or skilled machinists. Always clean contact surfaces thoroughly before wringing blocks together to prevent damage to lapped surfaces. Store in a controlled environment away from temperature extremes and humidity to maintain dimensional integrity. Do not drop or slide blocks across hard surfaces, as surface damage will compromise accuracy.
