Mitutoyo 611180-541 Steel Gage Block 0.14 in Grade AS-1

Product Description

The MITUTOYO 611180-541 is a rectangular steel gage block measuring 0.14 inches in overall length, manufactured to ASME Grade AS-1 accuracy standards. Gage blocks are precision-ground reference standards used to calibrate measuring instruments, verify part dimensions, and establish precise dimensional references on surface plates and in inspection fixtures. This block ships with a Certificate of Inspection, confirming it meets the dimensional tolerances required for Grade AS-1 classification. It is a standard item for metrology labs, quality control departments, toolrooms, and production inspection environments where traceable dimensional accuracy is required.

This gage block is suited for use in dimensional inspection and calibration workflows across manufacturing, machining, and precision assembly environments. The rectangular geometry allows stacking with other gage blocks to build up specific target dimensions. A Certificate of Inspection is included, supporting documentation requirements for ISO and ASME-compliant inspection processes. It is typically used by quality technicians, metrologists, and precision machinists.

Key Features

• Grade AS-1 accuracy per ASME standards for close-tolerance dimensional reference work
• Steel construction provides durability and stability for repeated use in shop and lab environments
• 0.14-inch nominal size for building precise dimensional stacks
• Includes Certificate of Inspection for traceable calibration documentation
• Rectangular form compatible with standard gage block accessories and holders

Compatibility

Designed as an OEM-style replacement and standard-issue precision reference block compatible with conventional rectangular gage block sets and accessories conforming to ASME B89.1.9 dimensional and form standards.

Installation Notes

Gage blocks should be handled by metrology technicians or trained quality personnel. Clean block surfaces thoroughly with an appropriate solvent before use to remove oils and debris that can affect accuracy. Store blocks in their protective case when not in use to prevent corrosion and surface damage. Never use gage blocks as general-purpose shims or cutting tools, as this will compromise calibrated surfaces.
