Mitutoyo 614191-531 Square Steel Gage Block 0.1 in Grade 0

Product Description

The MITUTOYO 614191-531 is a square steel gage block measuring 0.1 inches in overall length, manufactured to Grade 0 accuracy. Gage blocks are precision ground and lapped reference standards used to calibrate measuring instruments, set up comparators, and verify dimensional accuracy in machining and inspection environments. This block meets ASME standards and ships with a Certificate of Inspection, making it suitable for use in quality control labs, tool rooms, and production floor inspection stations. Grade 0 designates a high level of dimensional accuracy, appropriate for demanding calibration and inspection work.

This gage block is used in metrology and precision measurement applications across manufacturing, machine shops, and inspection facilities. It serves as a dimensional reference for calibrating micrometers, calipers, height gages, and comparators. The square profile allows for stacking and wringing with compatible blocks in a gage block set. Typical users include quality control technicians, tool and die makers, and metrology lab personnel working to ASME inspection protocols.

Key Features

• Steel construction for durability and dimensional stability
• 0.1 inch nominal size, precisely ground and lapped
• Includes Certificate of Inspection for traceability documentation
• Square profile supports wringing and stacking with compatible gage block sets

Compatibility

Designed as an OEM-style precision reference block compatible with standard square gage block sets and accessories conforming to ASME gage block specifications.

Installation Notes

Gage blocks are handled and set up by metrology technicians or qualified inspection personnel. Clean all mating surfaces before wringing blocks together to prevent surface damage and ensure accurate stacking. Store blocks in a protective case away from moisture and temperature extremes to preserve dimensional stability. Do not drop or stack blocks carelessly, as nicks or burrs will compromise accuracy.
