Mitutoyo 611173-541 Steel Gage Block 0.133 in Grade AS-1

Product Description

The MITUTOYO 611173-541 is a rectangular steel gage block measuring 0.133 inches, manufactured to ASME Grade AS-1 accuracy standards. Gage blocks are precision reference standards used to calibrate measurement instruments, set comparators, and verify dimensional accuracy in machining and inspection 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 toolroom and production inspection work. Licensed metrology technicians, machinists, and quality control inspectors are the primary users of gage blocks of this type.

This gage block is suited for use in machine shops, manufacturing facilities, and calibration laboratories where precise dimensional references are required. It functions as a single-block reference at the 0.133-inch nominal size and can be wrung with other gage blocks to build up composite measurements. Applications include setting up CMMs, micrometers, and comparator gauges, as well as verifying part dimensions during production inspection. It is appropriate for both general toolroom use and light metrology lab work.

Key Features

• Grade AS-1 accuracy per ASME standards for reliable dimensional reference
• Rectangular steel construction for durability and long service life
• 0.133-inch nominal size enables specific incremental measurement setups
• Includes Certificate of Inspection for traceability documentation
• Compatible with standard gage block wringing techniques for composite stacks

Compatibility

Designed as a standard rectangular steel gage block suitable for use with any ASME-compliant gage block set or accessory holder accepting blocks of 0.133-inch nominal size.

Installation Notes

Gage blocks should be handled by qualified metrology or inspection personnel using proper gage block handling practices. Store blocks in their protective case when not in use to prevent corrosion and surface damage. Clean contact faces with an appropriate gage block cleaning solution before wringing. Follow ASME B89.1.9 guidelines for handling, storage, and calibration intervals.
