Mitutoyo 611118-541 Steel Gage Block 0.18 in Grade AS-1

Product Description

The MITUTOYO 611118-541 is a rectangular steel gage block measuring 0.18 inches in length, manufactured to Grade AS-1 accuracy per ASME standards. Gage blocks are precision reference standards used to calibrate measuring instruments, set comparators, and verify dimensional accuracy in machining and inspection environments. Each block is supplied with a Certificate of Inspection, confirming it has been verified to AS-1 tolerances. This grade is suitable for shop-floor and inspection-room use where high dimensional accuracy is required. Metrology technicians, tool and die makers, and quality control professionals are the primary users.

This gage block is suited for dimensional calibration and measurement verification tasks in manufacturing, machining, and quality assurance settings. It serves as a reference standard for setting dial indicators, height gages, and other precision measuring equipment. The 0.18-inch size makes it useful as a single-block reference or as part of a wringing combination in a gage block set. Applications span both light industrial and precision shop environments where ASME-compliant reference standards are required.

Key Features

• Grade AS-1 accuracy per ASME standards for reliable dimensional reference
• Rectangular steel construction provides durability and resistance to wear
• 0.18-inch nominal length with five-decimal precision specification
• Includes Certificate of Inspection for traceability and compliance documentation
• Single-block packaging suitable for replacement or supplemental use in existing sets

Compatibility

Designed as an ASME-compliant Grade AS-1 rectangular steel gage block for use in standard metrology and dimensional inspection applications.

Installation Notes

Gage blocks are handled and set by metrology technicians and quality control personnel rather than installed in a mechanical system. Blocks should be cleaned with an appropriate solvent and lint-free cloth before use to prevent contamination of the measuring surfaces. Wring blocks together using proper technique to avoid surface damage. Store in the supplied case away from temperature extremes to maintain dimensional stability.
