Mitutoyo 614181-531 Square Steel Gage Block 0.141 in Grade 0

Product Description

The MITUTOYO 614181-531 is a square steel gage block measuring 0.141 inches, manufactured to Grade 0 accuracy and supplied with a Certificate of Inspection. Gage blocks are precision-ground reference standards used to calibrate measuring instruments, set comparators, and verify dimensional tolerances in metrology and quality control environments. Grade 0 designates a high level of dimensional accuracy per ASME standards, making this block appropriate for toolroom calibration and inspection work. Machinists, metrologists, and quality technicians typically keep these on hand as traceable reference pieces for day-to-day measurement verification.

This gage block is suited for use in tool and die shops, quality inspection labs, and manufacturing facilities where precise dimensional references are required. It fits into standard gage block set workflows, functioning as an individual block for selective stacking or as a replacement for a worn or damaged block of the same nominal size. The 0.141-inch size is a common increment used in building up composite stacks for a wide range of target dimensions.

Key Features

• Grade 0 accuracy per ASME standards for high-precision dimensional reference
• Square geometry for stable wringing and stacking with compatible blocks
• Steel construction for durability and dimensional stability
• Includes Certificate of Inspection for traceability documentation
• 0.141-inch nominal size supports a wide range of composite stack combinations

Compatibility

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

Installation Notes

Gage blocks are handled and stored by metrology or quality control personnel, not field-installed by trade technicians. Clean mating surfaces thoroughly before wringing to prevent scoring or false readings. Store in a protective case away from humidity and temperature extremes to preserve dimensional integrity. Never drop or stack gage blocks without proper wringing technique, as this can damage lapped surfaces.
