Mitutoyo 611182-531 Steel Gage Block 0.142 in Grade 0

Product Description

The MITUTOYO 611182-531 is a rectangular steel gage block measuring 0.142 inches in length, manufactured to Grade 0 accuracy and conforming to ASME standards. Gage blocks are precision-ground reference standards used to establish, verify, or calibrate linear measurements in tool rooms, metrology labs, and production quality control environments. This block ships with a Certificate of Inspection, confirming dimensional accuracy at the Grade 0 tolerance level. Grade 0 represents a high-accuracy classification appropriate for laboratory and inspection use. The steel construction provides durability and dimensional stability across typical shop temperature ranges.

This gage block is suited for use in dimensional inspection stations, surface plate setups, and calibration workflows. Metrology technicians, quality inspectors, and tool room machinists use blocks like this one to verify gauges, set comparators, and establish height references. The 0.142-inch size is a standard increment block commonly combined with other blocks in a wringing stack to achieve composite measurement targets. It is sold individually, making it a practical replacement for a lost or damaged block within an existing set.

Key Features

• Grade 0 accuracy classification per ASME standards — suitable for laboratory and precision inspection use
• Steel construction for dimensional stability and long service life
• 0.142-inch nominal length, ground and lapped to tight tolerances
• Includes Certificate of Inspection for traceability documentation
• Rectangular form compatible with standard wringing and stacking techniques
• Sold as a single block for targeted replacement or supplemental use

Compatibility

Designed as an individual replacement or supplemental gage block compatible with standard rectangular steel gage block sets conforming to ASME B89.1.9 or equivalent specifications.

Installation Notes

Gage blocks are handled and used by metrology technicians and quality control personnel. Always clean wringing surfaces with an approved gage block cleaning solution before and after use to prevent corrosion and contamination. Store blocks in a protective case away from heat sources and humidity. Apply a light coat of approved rust-preventive oil when blocks will be stored for extended periods.
