Mitutoyo 614218-531 Square Steel Gage Block 0.85 in Grade 0

Product Description

The MITUTOYO 614218-531 is a square steel gage block measuring 0.85 inches in overall length, manufactured to Grade 0 accuracy. Gage blocks are precision-ground reference standards used to calibrate measuring instruments, verify machine setups, and establish traceable dimensional baselines in metrology and machining environments. This block meets ASME standards and ships with a Certificate of Inspection, making it suitable for quality assurance workflows that require documented traceability. Licensed metrology technicians, machinists, and calibration lab personnel are the primary users.

This gage block is used in dimensional calibration labs, machine shops, and tool rooms where Grade 0 accuracy is required. It serves as a reference standard for setting comparators, height gages, micrometers, and other precision measuring instruments. The 0.85-inch size fills a specific increment in a gage block set or functions as a standalone reference piece for fixtures and setups requiring that exact nominal dimension.

Key Features

• Grade 0 accuracy per ASME standards for tight-tolerance metrology applications
• Square steel construction provides durability and consistent wringing characteristics
• 0.85-inch nominal size for precise dimensional reference
• Includes Certificate of Inspection for traceable calibration documentation
• Conforms to ASME standards for dimensional gage blocks

Compatibility

Designed as an OEM-style precision reference standard compatible with standard gage block accessory sets and holders sized for square-style steel gage blocks.

Installation Notes

Gage blocks should be handled by metrology technicians or qualified calibration personnel. Store blocks in a clean, controlled environment to prevent corrosion and surface damage. Before use, clean wringing surfaces with a lint-free cloth and appropriate gage block cleaning solution. Never drop or stack gage blocks carelessly, as surface damage will compromise accuracy and render the block out of tolerance.
