Mitutoyo 611119-541 Steel Gage Block 0.19 Inches AS-1

Product Description

The MITUTOYO 611119-541 is a rectangular steel gage block manufactured to ASME AS-1 accuracy grade standards. Gage blocks are precision-ground reference standards used to calibrate measuring instruments, set comparators, and verify dimensional tolerances in machining and inspection environments. This block measures 0.19 inches in overall length and is constructed from steel for dimensional stability and wear resistance. Each unit ships with a Certificate of Inspection, providing documented traceability for quality-control and calibration records. Metrology technicians, tool-and-die shops, and quality assurance departments rely on gage blocks of this grade for high-accuracy measurement applications.

This gage block is suited for dimensional inspection, instrument calibration, and precision layout work in manufacturing, machine shops, and metrology labs. AS-1 accuracy grade meets ASME standards, making it appropriate for applications where tight dimensional verification is required. The rectangular form allows for wringing with other gage blocks to build up custom reference dimensions. It is typically used by quality control inspectors and precision machinists working to close tolerances.

Key Features

• AS-1 accuracy grade per ASME standards for high-precision reference use
• 0.19-inch overall length in rectangular form factor
• Steel construction provides dimensional stability and resistance to wear
• Includes Certificate of Inspection for traceability documentation
• Rectangular geometry supports wringing with other gage blocks to build stacked reference dimensions

Compatibility

Designed as an OEM-style precision reference standard compatible with standard gage block sets and wringing assemblies meeting ASME gage block specifications.

Installation Notes

Gage blocks should be handled by metrology technicians or qualified quality control personnel familiar with precision measurement practices. Keep blocks clean and free of burrs, debris, or corrosion before use, as surface contamination affects accuracy. Store in a controlled environment away from temperature extremes to maintain dimensional stability. Follow ASME B89.1.9 guidelines for proper handling, wringing technique, and calibration interval management.
