Mitutoyo 614155-531 Square Steel Gage Block 0.115 in Grade 0

Product Description

The MITUTOYO 614155-531 is a square steel gage block measuring 0.115 inches, manufactured to Grade 0 accuracy. Gage blocks are precision-ground reference standards used to calibrate measuring instruments, set up comparators, and verify dimensional accuracy in machine shops, metrology labs, and quality-control environments. This block meets ASME standards and includes a Certificate of Inspection, confirming that the piece has been verified against traceable dimensional tolerances. Grade 0 indicates a high level of dimensional accuracy, making this block appropriate for calibration and inspection work where tight tolerances are required.

This gage block is suited for use in precision metrology, tool-and-die, and manufacturing quality-control applications. It serves as a reference standard when calibrating micrometers, calipers, height gages, and comparators. Machinists, metrologists, and quality technicians working in both production and inspection environments typically use blocks of this type to establish reliable reference dimensions on the shop floor or in a temperature-controlled lab setting.

Key Features

• Grade 0 accuracy meets ASME standards for calibration and inspection use
• Steel construction provides dimensional stability and wear resistance
• 0.115-inch nominal size for precise reference measurement
• Includes Certificate of Inspection for traceability documentation
• Square block geometry compatible with standard gage block accessories and holders

Compatibility

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

Installation Notes

Gage blocks are handled and stored by metrology technicians or precision machinists. Before use, clean mating surfaces with an appropriate gage-block cleaning solution and lint-free cloth to remove oils and debris that can affect accuracy. Wring blocks together using gentle sliding pressure rather than forcing them into contact. Store blocks in their protective case away from moisture and extreme temperature swings to prevent corrosion and dimensional drift.
