Mitutoyo 611121-531 Steel Gage Block 0.1001 in Grade 0

Product Description

The MITUTOYO 611121-531 is a rectangular steel gage block ground and lapped to a nominal length of 0.1001 inches at Grade 0 accuracy. Gage blocks serve as the fundamental length reference in precision measurement and quality control environments. This block is used to calibrate micrometers, calipers, and comparators, or to set up precision fixtures and machine tools. Grade 0 indicates a high level of dimensional accuracy suitable for inspection and calibration work. A Certificate of Inspection is included, confirming the block has been verified against traceable standards. Metrology technicians, quality engineers, and tool-room machinists are the primary users.

This gage block is suited for use in tool rooms, inspection labs, and manufacturing quality departments. Its steel construction makes it appropriate for general-purpose dimensional reference tasks. Single-block packaging supports targeted replacement of worn or damaged blocks within an existing set without purchasing a full set. It meets ASME standards, making it appropriate for facilities that require documented dimensional traceability in their measurement systems.

Key Features

• Grade 0 accuracy per ASME standards for inspection and calibration use
• Nominal length of 0.1001 inches for precise dimensional reference
• Steel construction for durability and wear resistance in shop environments
• Rectangular form compatible with standard wringing and stacking techniques
• Includes Certificate of Inspection for traceability documentation
• Single-unit packaging allows individual block replacement

Compatibility

Designed as a standard rectangular steel gage block for use with ASME-compliant gage block sets and accessories including holders, jaws, and scribers used in tool room and inspection applications.

Installation Notes

Gage blocks should be handled with clean, dry hands or lint-free gloves to prevent corrosion from skin oils. Before wringing blocks together or using them as a reference, clean all mating surfaces with a lint-free cloth and appropriate cleaning solution. Store blocks in their protective case when not in use and avoid dropping or stacking them on hard surfaces. Periodic recalibration against a certified reference standard is recommended to maintain measurement integrity.
