Mitutoyo 611181-541 Steel Gage Block 0.141 in Grade AS-1

Product Description

The MITUTOYO 611181-541 is a rectangular steel gage block measuring 0.141 inches in overall length, manufactured to ASME Grade AS-1 accuracy standards. Gage blocks serve as precision reference standards for calibrating measuring instruments, setting comparators, and verifying dimensional tolerances in machining and metrology applications. Each block ships with a Certificate of Inspection confirming it meets the stated accuracy grade. This part is appropriate for use in tool rooms, quality labs, and production floor inspection stations where traceable dimensional references are required.

Grade AS-1 gage blocks are suitable for inspection and calibration work in environments where close tolerance verification is routine. This block is used as a single-piece reference standard or as part of a wrung set. Typical users include machinists, metrologists, and quality control technicians working in precision manufacturing, aerospace, automotive, and general industrial settings.

Key Features

• Grade AS-1 accuracy per ASME standards for reliable dimensional reference
• Rectangular steel construction for durability and wringing compatibility
• 0.141-inch nominal size for specific stack-up and calibration applications
• Includes Certificate of Inspection for traceability documentation
• Single-piece packaging suitable for individual replacement or set supplementation

Compatibility

Designed as an OEM-style precision reference standard compatible with standard gage block sets and accessories requiring rectangular steel blocks conforming to ASME Grade AS-1 specifications.

Installation Notes

Gage blocks are handled and used by metrologists and quality technicians, not typically installed in the mechanical sense. Clean block surfaces thoroughly before wringing to remove oils, debris, and fingerprints. Store blocks in a controlled environment away from humidity and temperature extremes to prevent corrosion and dimensional drift. Follow ASME B89.1.9 handling and storage guidelines to maintain calibration integrity.
