Mitutoyo 614203-531 Square Steel Gage Block 3 in Grade 0

Product Description

The MITUTOYO 614203-531 is a square steel gage block nominally sized at 3.00000 inches, manufactured to Grade 0 accuracy standards. Gage blocks serve as dimensional reference standards used to calibrate measuring instruments, set comparators, and verify the accuracy of machined parts. This block is made from steel and conforms to ASME standards for gage block accuracy. It ships with a Certificate of Inspection, confirming that the individual block has been measured and verified against traceable standards. Calibration technicians, quality control professionals, and precision machinists are the primary users of this type of equipment.

Square gage blocks in Grade 0 are suited for laboratory and quality assurance environments where close dimensional tolerances must be maintained. The Grade 0 designation under ASME standards indicates tighter allowable deviation than Grade 1 or Grade 2 blocks, making this block appropriate for reference-grade calibration work. It is used in both production metrology settings and calibration labs that require traceable dimensional standards for instrument verification and process control.

Key Features

• Grade 0 accuracy per ASME standards for high-precision dimensional reference
• Nominal size of 3.00000 inches for repeatable, traceable measurement setups
• Steel construction for durability and dimensional stability
• Includes Certificate of Inspection with each block
• Square geometry suitable for stacking and wringing with compatible block sets

Compatibility

Designed as an OEM-style reference standard for use with standard gage block sets and accessories conforming to ASME B89.1.9 square gage block specifications.

Installation Notes

Gage blocks are handled by calibration technicians and metrologists rather than installed in the field. Store blocks in a controlled environment to minimize thermal expansion effects on dimensional readings. Clean contact surfaces before wringing to prevent surface damage or inaccurate stacking. Follow your facility or laboratory quality system procedures for handling, storage, and recalibration intervals.
