Mitutoyo 614174-531 Square Steel Gage Block 0.134 in Grade 0

Product Description

The MITUTOYO 614174-531 is a square steel gage block measuring 0.134 inches, manufactured to Grade 0 accuracy. Gage blocks serve as the dimensional reference standard in precision measurement work, providing a certified flat and parallel surface used to calibrate instruments, set comparators, and verify workpiece dimensions. This block ships with a Certificate of Inspection, confirming it meets Grade 0 tolerances as defined by ASME standards. Grade 0 represents a high level of dimensional accuracy, making it appropriate for laboratory, tool room, and quality control environments where tight measurement traceability is required.

This gage block is suited for use in precision metrology applications across manufacturing, machining, and inspection settings. It is used by quality control technicians, tool and die makers, and metrologists who need a reliable reference standard at the 0.134-inch nominal size. Common tasks include setting dial indicators, zeroing comparators, and building gage block stacks for custom measurement setups. The block is appropriate for both shop floor and controlled metrology lab environments.

Key Features

• Grade 0 accuracy per ASME standards, suitable for precision reference and calibration use
• Square steel construction provides durability and wear resistance for repeated wringing and handling
• 0.134-inch nominal size for use in stacked or standalone measurement setups
• Includes Certificate of Inspection for traceability documentation
• Individual unit packaging for single-block purchase and storage

Compatibility

Designed as an individual Grade 0 square steel gage block for use in standard gage block sets, stacks, and precision measurement applications conforming to ASME specifications.

Installation Notes

Gage blocks are handled and set up by metrology technicians, quality control personnel, and skilled machinists. Before use, clean mating surfaces thoroughly to remove oil, debris, or burrs that can affect wringing adhesion and measurement accuracy. Store blocks in their protective case when not in use to prevent corrosion and surface damage. Do not drop or strike blocks against hard surfaces, as this can alter dimensional accuracy.
