Mitutoyo 611202-531 Steel Gage Block 2 in Grade 0

Product Description

The MITUTOYO 611202-531 is a rectangular steel gage block manufactured to Grade 0 accuracy and sized at exactly 2.00000 inches. Gage blocks are precision-ground reference standards used to calibrate measuring instruments, set up comparators, and verify dimensional tolerances in metrology and quality control applications. This block ships with a Certificate of Inspection, confirming it meets dimensional accuracy requirements at the Grade 0 level as defined by ASME standards. It is used by metrology technicians, machinists, and quality assurance professionals who need a traceable, high-accuracy length reference for precision measurement work.

This gage block is suited for tool rooms, calibration labs, manufacturing inspection departments, and machine shops where close-tolerance measurement verification is required. Grade 0 blocks are appropriate for high-precision inspection tasks and instrument calibration. The block is manufactured from steel, which provides durability and dimensional stability under typical shop and lab conditions. It is sold individually and is compatible with standard rectangular gage block accessories including holders and wringing fixtures.

• Nominal size of 2.00000 inches for use as a traceable length reference
• Steel construction for dimensional stability and long service life
• Includes Certificate of Inspection for traceability documentation
• Rectangular form compatible with standard gage block holders and wringing setups

Compatibility

Designed as an OEM-style replacement or direct-use rectangular gage block compatible with standard ASME-specification gage block sets and accessories used in metrology and inspection applications.

Installation Notes

Gage blocks are handled and stored by metrology technicians and quality control personnel — they are not installed in a traditional sense but must be wrung, stored, and handled according to established metrology practices. Clean contact surfaces thoroughly before wringing to avoid dimensional error or surface damage. Store blocks in a protective case away from moisture and temperature extremes to maintain calibration integrity. Periodic recalibration against a traceable standard is recommended per your facility's quality management program.
