Mitutoyo 614126-531 Steel Gage Block 0.1006 in Grade 0

Product Description

The MITUTOYO 614126-531 is a square steel gage block measuring 0.1006 inches, manufactured to Accuracy Grade 0 — the tightest tolerance class defined under ASME standards. Gage blocks are precision-ground reference standards used to calibrate measuring instruments, set comparators, and verify dimensional accuracy in quality control and metrology applications. Each block ships with a Certificate of Inspection, confirming dimensional traceability. Grade 0 blocks are appropriate for calibration labs and inspection environments where the highest level of dimensional certainty is required. This block weighs 1 pound and is sold individually.

This gage block is suited for use in machine shops, inspection departments, tool rooms, and calibration laboratories. It serves as a reference standard when setting up micrometers, calipers, height gages, and surface plate comparators. The 0.1006-inch size fills a common step increment in inch-series gage block sets and is frequently used as a standalone reference block or as a wringing component in a stacked block combination to achieve a precise target dimension.

Key Features

• Accuracy Grade 0 per ASME standards — highest precision class for calibration and inspection use
• Steel construction provides long service life and resistance to wear on measuring surfaces
• 0.1006-inch nominal length suits common inch-series dimensional reference requirements
• Includes Certificate of Inspection for dimensional traceability documentation
• Square block geometry supports stable wringing and stacking with other blocks

Compatibility

Designed as an OEM-style precision reference standard compatible with inch-series gage block sets and comparator setups used in general metrology and dimensional inspection applications.

Installation Notes

Gage blocks are handled and set up by calibration technicians and quality control inspectors, not installed in the traditional sense. Wringing surfaces must be clean and free of debris before contact to avoid damage or inaccurate reference readings. Store blocks in their protective case when not in use and avoid contact with abrasive surfaces. Handle with lint-free gloves to prevent corrosion from skin oils on the lapped surfaces.
