Mitutoyo 614208-531 Square Steel Gage Block 8 in Grade 0

Product Description

The MITUTOYO 614208-531 is a square steel gage block with an overall length of 8 inches, manufactured to Grade 0 accuracy. Gage blocks are precision-ground reference standards used to calibrate measuring instruments, set comparators, and verify dimensional accuracy in metrology and quality control applications. This block meets ASME standards and ships with a Certificate of Inspection. Grade 0 represents a high level of dimensional accuracy, making this block appropriate for calibration labs and precision inspection work where tight tolerances must be verified and documented.

This gage block is suited for use in precision measurement environments including manufacturing inspection departments, tool rooms, and calibration laboratories. It serves as a dimensional reference standard for calibrating micrometers, height gauges, snap gauges, and other precision measuring tools. The 8-inch size makes it useful for setting up large-range comparators and verifying longer-travel instruments. Installation and use are handled by metrology technicians, quality engineers, and skilled machinists following applicable ASME standards.

Key Features

• Grade 0 accuracy per ASME standards for high-precision reference applications
• Square steel construction machined to 8.00000 inches nominal length
• Includes Certificate of Inspection for traceability documentation
• ASME-compliant for use in regulated calibration and inspection programs
• Single-piece package ready for immediate use in metrology setups

Compatibility

Designed as an OEM-style precision reference standard compatible with comparator setups, surface plates, and measuring instrument calibration workflows that require an 8-inch Grade 0 gage block per ASME specifications.

Installation Notes

Gage blocks are handled and set up by metrology technicians and quality control personnel in controlled measurement environments. Clean the block and mating surfaces thoroughly before wringing or stacking to prevent surface damage and measurement error. Store in the provided case away from temperature extremes to maintain dimensional stability. Do not use this block as a mechanical stop or structural component, as surface damage will compromise accuracy.
