Mitutoyo 614165-531 Square Steel Gage Block 0.125 in Grade 0

Product Description

The MITUTOYO 614165-531 is a square steel gage block used for dimensional measurement, calibration, and inspection work across manufacturing, machining, and metrology applications. Measuring 0.125 inches in overall length, this block is manufactured to Accuracy Grade 0, which represents a high level of dimensional precision suitable for critical measurement tasks. A Certificate of Inspection is included with each block, confirming conformance to stated accuracy specifications. This type of gage block is a standard reference tool used by machinists, quality technicians, and calibration specialists who require traceable, reliable dimensional standards on the shop floor or in the lab.

Grade 0 square steel gage blocks are used in tool rooms, quality control labs, and precision machining environments. They serve as reference standards for setting comparators, verifying instrument accuracy, and establishing dimensional benchmarks during production inspection. The 0.125-inch size is a common increment used in gage block sets and as a standalone reference in setups requiring precise short-dimension standards. This block is appropriate for both shop floor and controlled metrology environments.

Key Features

• Accuracy Grade 0 construction for high-precision dimensional reference work
• 0.125-inch overall length provides a precise short-dimension standard
• Steel construction for durability and dimensional stability under normal handling conditions
• Meets ASME standards for gage block accuracy and geometry
• Includes Certificate of Inspection confirming dimensional conformance

Compatibility

Designed as a standalone or supplemental reference standard compatible with standard gage block accessories, holders, and comparator setups used in precision metrology and machining inspection workflows.

Installation Notes

Gage blocks are handled and set up by calibration technicians, metrologists, and precision machinists. Always clean contact surfaces thoroughly before wringing or stacking blocks to prevent dimensional error and surface damage. Store in the supplied case or a clean, dry environment to prevent corrosion and dimensional drift. Follow ASME B89.1.9 guidelines for proper handling, cleaning, and storage of gage blocks.
