Mitutoyo 611150-531 Steel Gage Block 0.11 in Grade 0

Product Description

The MITUTOYO 611150-531 is a rectangular steel gage block with a nominal size of 0.11 inches and an accuracy rating of Grade 0. Gage blocks are precision-ground reference standards used to calibrate measuring instruments, set comparators, and verify dimensional tolerances in manufacturing and metrology environments. This block ships with a Certificate of Inspection, confirming it meets the stated accuracy grade at the time of manufacture. Grade 0 represents a high level of dimensional precision, making this block appropriate for toolroom and inspection applications where tight tolerance verification is required. Machinists, metrologists, and quality technicians are the primary users.

This gage block is suited for use in toolrooms, quality labs, and production inspection environments. It functions as a length reference for calibrating micrometers, calipers, height gages, and comparators. The rectangular form factor is the standard geometry for individual gage blocks and slip gage sets. It is appropriate for both standalone use and as part of a wringing stack to build up composite dimensions. Facilities operating under ASME standards will find this block compliant with applicable dimensional accuracy requirements.

Key Features

• Grade 0 accuracy rating meets ASME gage block standards for toolroom and inspection use
• Steel construction provides durability and dimensional stability in typical shop and lab environments
• Nominal size of 0.11 inches supports a wide range of stack-up and calibration applications
• Includes Certificate of Inspection for traceability documentation
• Rectangular form factor is compatible with standard wringing and stacking techniques

Compatibility

Designed as an individual rectangular gage block for use in toolroom calibration, inspection setups, and gage block sets conforming to ASME dimensional standards.

Installation Notes

Gage blocks are handled and stored by metrology technicians and quality assurance personnel, not typically installed in a mechanical system. Blocks should be cleaned of preservative oil and wrung or placed in a temperature-stable environment prior to use to allow thermal stabilization. Avoid dropping or sliding blocks across hard surfaces, as edge damage will affect accuracy. Store in the supplied case or a clean, dry environment to prevent corrosion of the steel surfaces.
