Mitutoyo 611171-541 Steel Gage Block 0.131 in Grade AS-1

Product Description

The MITUTOYO 611171-541 is a rectangular steel gage block measuring 0.131 inches in overall length, manufactured to ASME Grade AS-1 accuracy standards. Gage blocks are precision reference standards used to calibrate measuring instruments, set up comparators, and verify dimensional accuracy in metrology and machining environments. This block includes a Certificate of Inspection, confirming it has been verified against traceable standards. Grade AS-1 represents a high level of dimensional accuracy suitable for demanding inspection and calibration work. Machinists, quality control technicians, and calibration professionals are the primary users of this type of reference standard.

This gage block is suited for use in tool rooms, quality labs, and production inspection environments where precise dimensional verification is required. It functions as a reference for setting height gages, dial indicators, and other comparative measuring instruments. The 0.131-inch size makes it a useful increment block within a standard inch gage block set or as a standalone reference for specific measurement setups.

Key Features

• Grade AS-1 accuracy per ASME standards for reliable calibration reference
• Steel construction for durability and dimensional stability
• 0.131-inch nominal size for precise incremental measurement setups
• Includes Certificate of Inspection for traceability documentation
• UNSPSC Code 41111600 classified precision measuring instrument

Compatibility

Designed as an OEM-style precision reference standard compatible with standard inch gage block sets and accessories conforming to ASME B89.1.9 specifications for gage blocks.

Installation Notes

Gage blocks are handled by metrology and quality control technicians and do not require mechanical installation. Store blocks in their protective case and handle with clean, lint-free gloves to prevent corrosion from skin oils. Wring blocks together using light pressure and a sliding motion; never force or snap blocks together. Clean and apply a thin film of protective oil after each use to maintain surface integrity.
