Mitutoyo 611119-531 Steel Gage Block 0.19 in Grade 0

Product Description

The MITUTOYO 611119-531 is a rectangular steel gage block measuring 0.19 inches in overall length, manufactured to Grade 0 accuracy. Gage blocks are precision measurement standards used to calibrate instruments, set comparators, and verify dimensional tolerances on the shop floor or in a metrology lab. This block meets ASME standards and ships with a Certificate of Inspection, confirming it has been verified against traceable reference standards. Grade 0 indicates a high level of dimensional accuracy appropriate for inspection and calibration work. Machinists, quality technicians, and metrology professionals use blocks like this as a reliable reference when tight tolerances must be confirmed or transfer-calibrated to measuring tools.

This gage block is suited for use in precision measurement applications across manufacturing, tool and die, aerospace, and general industrial environments. It is appropriate for both laboratory settings and production floor inspection stations where dimensional verification of machined parts is required. The compact 0.19-inch size makes it useful as a single-size reference or as a component within a gage block set when wringing blocks together to achieve specific stack dimensions.

Key Features

• Grade 0 accuracy per ASME standards for high-precision calibration and inspection use
• Steel construction provides durability and wear resistance in production and lab environments
• 0.19-inch nominal size suitable for single use or wringing into block stacks
• Includes Certificate of Inspection for traceability documentation
• Rectangular geometry conforms to standard gage block form factor

Compatibility

Designed as an OEM-style precision reference block compatible with standard rectangular gage block accessories including gage block holders, scribing clamps, and wringing fixtures that accept blocks of this nominal size and form factor.

Installation Notes

Gage blocks are handled and stored by metrology technicians and quality inspectors. Always clean contact surfaces with an appropriate gage block cleaning solution and lint-free cloth before and after use to prevent corrosion and ensure accurate wringing. Store blocks in their designated case away from temperature extremes to minimize thermal expansion effects on measurement readings. Do not drop, slide across hard surfaces, or allow contact with abrasive materials, as surface damage will compromise accuracy.
