Mitutoyo 611193-531 Steel Gage Block 0.3 in Grade 0

Product Description

The MITUTOYO 611193-531 is a rectangular steel gage block measuring 0.3 inches in length, manufactured to Grade 0 accuracy. Gage blocks are precision reference standards used to calibrate measuring instruments, set comparators, and verify dimensional tolerances on the shop floor or in a metrology lab. This block ships with a Certificate of Inspection, confirming it meets ASME dimensional accuracy requirements for Grade 0. Grade 0 represents a high level of accuracy suitable for inspection and calibration work. It is handled by metrology technicians, quality engineers, and precision machinists who require traceable reference standards.

This gage block is suited for use in inspection rooms, tool rooms, and production environments where precise dimensional reference is required. It serves as a reference standard for setting dial indicators, micrometers, height gages, and similar instruments. The 0.3-inch size is a common increment in standard English gage block sets used in dimensional metrology under ASME standards. It is appropriate for both industrial manufacturing and laboratory calibration applications.

Key Features

• Grade 0 accuracy per ASME standards for high-precision dimensional reference
• Steel construction provides durability and dimensional stability
• 0.3-inch nominal length with five-decimal precision (0.30000 inches)
• Includes Certificate of Inspection for traceability documentation
• Rectangular form compatible with standard gage block wringing and stacking

Compatibility

Designed as an OEM-style precision reference standard compatible with standard rectangular gage block sets conforming to ASME dimensional specifications for English-unit metrology applications.

Installation Notes

Gage blocks are handled by metrology and quality control professionals. Clean wringing surfaces thoroughly before use to remove oils, debris, and burrs that could affect accuracy or damage the lapped faces. Store blocks in a protective case away from temperature extremes to minimize thermal expansion effects on dimensional readings. Do not drop or slide blocks across hard surfaces, as this will damage the precision lapped faces.
