Mitutoyo 611143-531 Steel Gage Block 0.103 in Grade 0

Product Description

The MITUTOYO 611143-531 is a rectangular steel gage block with a nominal size of 0.103 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 machining and inspection environments. Grade 0 represents a high level of dimensional accuracy per ASME standards, making this block suitable for use in tool rooms, quality labs, and metrology departments. A Certificate of Inspection is included, providing documented traceability for quality assurance and compliance requirements. Machinists, metrologists, and quality control technicians are the primary users of this type of precision measurement standard.

This gage block is intended for use in dimensional inspection and calibration applications in both industrial and precision manufacturing settings. It serves as a reference standard for setting dial indicators, height gages, and other comparative measuring instruments where verified dimensional accuracy is required. The 0.103-inch size makes it a single-block increment piece suitable for wringing into a set or using individually to establish a specific reference dimension on an inspection surface plate or similar setup.

Key Features

• Grade 0 accuracy per ASME standards for high-precision reference and calibration use
• Rectangular steel construction provides durability and stable dimensional integrity
• Nominal size of 0.103 inches enables precise incremental measurements and gage block stack combinations
• Includes Certificate of Inspection for traceable quality documentation
• Sold as a single block for targeted replacement or supplemental additions to an existing set

Compatibility

Designed as an OEM-style precision reference standard suitable for use with standard gage block sets and accessories conforming to ASME dimensional gage block specifications.

Installation Notes

Gage blocks are handled and used by metrologists, quality technicians, and skilled machinists in controlled inspection environments. Surfaces should be cleaned with an appropriate solvent and lint-free cloth before and after use to prevent corrosion and maintain flatness. Store blocks in a protective case away from temperature extremes to preserve dimensional stability. Do not drop or stack improperly, as surface damage will compromise accuracy.
