Mitutoyo 611142-541 Steel Gage Block 0.102 in Grade AS-1

Product Description

The MITUTOYO 611142-541 is a rectangular steel gage block measuring 0.102 inches in length, manufactured to Grade AS-1 accuracy standards per ASME specifications. Gage blocks are precision reference standards used to calibrate measuring instruments, set up comparators, and verify dimensional tolerances in quality control and manufacturing environments. This block ships with a Certificate of Inspection, confirming it has been measured and certified to Grade AS-1 tolerances. It is handled and used by metrology technicians, machinists, tool and die makers, and quality assurance professionals who require traceable dimensional standards for high-precision work.

This gage block is suited for use in tool rooms, quality labs, and on the shop floor wherever a calibrated reference dimension of 0.102 inches is required. Typical applications include setting dial indicators, height gauges, and snap gauges, as well as stacking with other gage blocks to build up compound measurements. Grade AS-1 accuracy makes it appropriate for inspection and general-purpose calibration tasks in both light manufacturing and precision machining environments.

Key Features

• Grade AS-1 accuracy per ASME standards for reliable dimensional reference
• Rectangular steel construction for durability and wear resistance
• 0.102-inch nominal size for precise dimensional setups
• Includes Certificate of Inspection for traceability documentation
• UNSPSC Code 41111600 — precision measuring instruments category

Compatibility

Designed as a standard rectangular gage block compatible with conventional gage block accessories including holders, jaws, and scribing points that accept ASME-specification steel blocks.

Installation Notes

Gage blocks should be handled by metrology or quality technicians using clean, lint-free gloves to prevent corrosion from skin contact. Store the block in its protective case when not in use and allow it to thermally stabilize to room temperature before taking reference measurements. Clean mating surfaces thoroughly before wringing blocks together. Do not drop or strike the block, as impact damage will compromise calibration accuracy.
