Mitutoyo 614149-531 Steel Gage Block 0.109 in Grade 0

Product Description

The MITUTOYO 614149-531 is a square steel gage block with a nominal length of 0.109 inches, manufactured to ASME Grade 0 accuracy standards. Gage blocks serve as dimensional reference standards used to calibrate measuring instruments, set comparators, and verify part tolerances on the shop floor and in metrology labs. Grade 0 designation indicates a high level of dimensional accuracy, making this block appropriate for calibration work and precision inspection tasks. It ships with a Certificate of Inspection confirming conformance to the stated accuracy grade. Machinists, metrologists, and quality technicians are the primary users of this type of reference standard.

This gage block is suited for use in precision measurement environments including machine shops, toolrooms, quality control labs, and manufacturing inspection stations. It is appropriate for applications requiring a small-dimension reference standard, such as setting dial indicators, air gauges, or comparator stands. The 0.109-inch block is commonly used as an individual reference piece or as part of a gage block set to build up a required dimension through wringing.

Key Features

• Grade 0 accuracy per ASME standards for high-precision dimensional reference
• Square steel construction provides durability and consistent wringing surfaces
• Nominal length of 0.109 inches for small-dimension calibration tasks
• Includes Certificate of Inspection for traceability documentation
• Single-piece packaging suitable for individual replacement or set completion

Compatibility

Designed as an individual gage block reference standard compatible with standard wringing sets and comparator setups conforming to ASME gage block specifications.

Installation Notes

Gage blocks are precision metrology tools and should be handled by qualified metrologists or inspection technicians. Clean contact surfaces thoroughly before wringing to avoid scratching or contaminating the lapped faces. Store in the provided case or a protected environment to prevent corrosion and surface damage. Do not drop or wring blocks under load, as this will compromise accuracy.
