Mitutoyo 611167-541 Steel Gage Block 0.127 in Grade AS-1

Product Description

The MITUTOYO 611167-541 is a rectangular steel gage block measuring 0.127 inches, manufactured to Grade AS-1 accuracy. Gage blocks are precision-ground reference standards used to calibrate measuring instruments, set comparators, and verify dimensional tolerances in metrology and quality control environments. This block conforms to ASME standards and includes a Certificate of Inspection. It is handled and used by metrologists, machinists, and quality technicians who require traceable, high-accuracy dimensional reference in production and lab settings.

This gage block is suited for use in machine shops, calibration laboratories, and inspection departments where tight dimensional verification is required. The 0.127-inch size fills a specific increment in a gage block set or serves as a standalone reference standard for setting up precision measurement equipment. Its rectangular form is the industry-standard geometry for wringing blocks together to build composite dimensions.

Key Features

• Grade AS-1 accuracy conforming to ASME standards for precision dimensional reference
• Steel construction provides durability and long service life under normal metrology lab conditions
• 0.127-inch nominal size for incremental or standalone dimensional reference
• Includes Certificate of Inspection for traceability documentation
• Rectangular geometry compatible with standard wringing technique for composite stack-ups

Compatibility

Designed as an OEM-style precision reference standard for use with standard rectangular gage block accessories, holders, and wringing films compatible with ASME-grade steel gage blocks.

Installation Notes

Gage blocks should be handled by calibration technicians or quality professionals following established metrology lab protocols. Clean mating surfaces thoroughly before wringing to prevent scratching or contamination. Store blocks in a controlled environment away from moisture and temperature extremes to maintain dimensional stability. Never drop or slide blocks across abrasive surfaces, as this will damage the lapped faces and compromise accuracy.
