Mitutoyo 614199-531 Square Steel Gage Block 0.9 in Grade 0

Product Description

The MITUTOYO 614199-531 is a square steel gage block measuring 0.9 inches, manufactured to Grade 0 accuracy standards. Gage blocks serve as dimensional reference standards used to calibrate measuring instruments and verify part dimensions on the shop floor or in a metrology lab. This block meets ASME standards and ships with a Certificate of Inspection, confirming its dimensional accuracy at time of manufacture. Precision machinists, quality control technicians, and metrology professionals rely on Grade 0 blocks where tight dimensional verification is required.

This gage block is suited for use in tool rooms, quality labs, and production environments where accurate length standards are needed for instrument calibration, comparator setups, and surface plate inspection work. Its square steel construction provides durability and wringing capability typical of professional-grade reference standards. It is appropriate for both in-process inspection and calibration of handheld measuring tools such as micrometers and calipers.

Key Features

• Grade 0 accuracy per ASME standards, suitable for calibration and high-precision inspection work
• Square steel construction provides long service life and reliable wringing surfaces
• Nominal size of 0.9 inches (0.90000 decimal inch) for precise dimensional reference
• Includes Certificate of Inspection confirming dimensional accuracy at time of manufacture
• Single-block packaging with minimum order quantity of one

Compatibility

Designed for use as a standalone dimensional reference standard compatible with standard gage block accessories, holders, and comparator setups used in ASME-compliant metrology applications.

Installation Notes

Gage blocks should be handled by metrology or quality control personnel familiar with wringing technique and proper storage practices. Clean and degrease the gage surfaces before wringing or use to prevent contamination and corrosion. Store in the provided case and away from temperature extremes to maintain dimensional stability. Avoid dropping or stacking with non-compatible materials, as surface damage will compromise accuracy.
