Mitutoyo 611214-531 Steel Gage Block 0.45 in Grade 0

Product Description

The MITUTOYO 611214-531 is a rectangular steel gage block with a nominal length of 0.45 inches and an ASME Grade 0 accuracy rating. Gage blocks are precision-ground reference standards used to calibrate measuring instruments, verify dimensional tolerances, and establish reference lengths on the shop floor or in a metrology lab. Grade 0 indicates a higher accuracy tier suited for calibration and inspection applications where tighter dimensional tolerance is required. This block ships with a Certificate of Inspection confirming it meets the stated accuracy grade. It is handled and used by machinists, quality technicians, metrologists, and tool room personnel.

This gage block is used in dimensional inspection and calibration workflows across manufacturing, tool rooms, and quality control labs. Typical applications include setting comparators and height gages, verifying machined part dimensions, and building gage block stacks for precise length references. Its steel construction makes it appropriate for general-purpose metrology work where a durable, stable reference block is needed.

Key Features

• Grade 0 accuracy per ASME standards for calibration-grade dimensional reference work
• Nominal length of 0.45 inches for use in precision gage block stacks
• Steel construction provides durability and stability under typical shop and lab conditions
• Includes Certificate of Inspection verifying conformance to stated accuracy grade
• Individual block sold as a single unit for targeted replacement or stack assembly

Compatibility

Designed as a standard rectangular gage block conforming to ASME specifications, compatible with other ASME-compliant gage block sets and accessories used in dimensional metrology and inspection applications.

Installation Notes

Gage blocks are precision instruments and should be handled by qualified metrology or inspection personnel. Always clean mating surfaces before wringing blocks together to prevent surface damage and measurement error. Store blocks in a protective case away from moisture and contaminants to prevent corrosion. Do not drop or impact gage blocks, as this can alter their calibrated dimensions.
