Mitutoyo 611155-531 Steel Gage Block 0.115 in Grade 0

Product Description

The MITUTOYO 611155-531 is a rectangular steel gage block measuring 0.115 inches, manufactured to Grade 0 accuracy. Gage blocks serve as dimensional reference standards used to calibrate measuring instruments, set up comparators, and verify part tolerances on the shop floor or in the metrology lab. This block conforms to ASME standards and includes a Certificate of Inspection, confirming that the block has been measured and verified at the stated grade. Grade 0 blocks are high-accuracy standards suited for demanding calibration and inspection work. Machinists, quality technicians, and metrologists are the primary users.

This gage block is used in precision measurement environments including manufacturing facilities, tool rooms, inspection labs, and calibration services. It functions as a reference standard for setting dial indicators, digital comparators, and height gages, as well as for verifying machine setups. The 0.115-inch dimension makes it suitable for use individually or in combination with other blocks in a wringing stack to achieve a target measurement. Single-block sets like this are commonly purchased as replacements or additions to existing gage block sets.

Key Features

• Grade 0 accuracy per ASME standards for high-precision dimensional reference
• Steel construction provides durability and stability in shop and lab environments
• 0.115-inch nominal size for use alone or in combination with other blocks
• Includes Certificate of Inspection for traceability documentation
• Rectangular form compatible with standard wringing techniques

Compatibility

Designed as a Grade 0 rectangular steel gage block conforming to ASME standards, suitable for use with standard gage block sets and accessories in metrology and inspection applications.

Installation Notes

Gage blocks are handled and used by quality technicians and metrologists. Always clean block surfaces thoroughly before wringing to prevent surface damage and ensure accurate stacking. Store blocks in their protective case when not in use to prevent corrosion and surface wear. Do not use gage blocks as mechanical stops or clamps, as this can compromise their accuracy grade.
