Mitutoyo 614143-531 Steel Gage Block 0.103 in Grade 0

Product Description

The MITUTOYO 614143-531 is a square steel gage block measuring 0.103 inches, manufactured to Grade 0 accuracy. Gage blocks are precision ground reference standards used to calibrate measuring instruments, verify tool dimensions, and establish accurate measurements in machine shops, metrology labs, and quality control environments. This block meets ASME standards and includes a Certificate of Inspection, confirming dimensional accuracy at the time of manufacture. Grade 0 designates a high level of dimensional tolerance, making this block appropriate for demanding calibration and inspection work. Installation is performed by calibration technicians and quality engineers.

This gage block is suited for use in precision measurement applications across manufacturing, tooling, and inspection settings. It serves as a reference standard when calibrating micrometers, calipers, height gages, and comparators. The 0.103-inch nominal size makes it a useful component in a wrung stack to achieve a target measurement. Typical users include machinists, metrologists, and quality control professionals in both job shop and production environments.

Key Features

Installation Notes

Gage blocks are handled and wrung together by calibration technicians and quality assurance professionals. Keep block surfaces clean and free of burrs before wringing to prevent damage to the lapped faces. Store in a protective case away from humidity and temperature extremes to maintain dimensional stability. Follow your facility's calibration interval schedule and applicable ASME B89 standards for gage block maintenance and recertification.
