Mitutoyo 614161-531 Square Steel Gage Block 0.121 in Grade 0

Product Description

The MITUTOYO 614161-531 is a square steel gage block with a nominal length of 0.121 inches, manufactured to Accuracy Grade 0 tolerances. Gage blocks are precision-ground reference standards used to establish or verify dimensional measurements across a range of metrology and quality-control applications. This block is supplied individually and includes a Certificate of Inspection, confirming dimensional compliance at the time of manufacture. Grade 0 blocks are suited for calibration labs, tool rooms, and inspection environments where tight measurement traceability is required. Qualified metrologists and precision machinists are the primary users of this product.

This gage block is appropriate for use in laboratory, inspection room, and production floor measurement applications wherever a ASME-compliant dimensional reference standard is needed. Its 0.121-inch nominal size makes it a useful step in building gage block stacks for setting comparators, calibrating micrometers, or verifying fixture dimensions. The included Certificate of Inspection supports quality management and traceability requirements common in aerospace, automotive, and general manufacturing environments.

Key Features

• Grade 0 accuracy for high-precision calibration and inspection use
• Steel construction for durability and wear resistance in repeated-use applications
• Nominal length of 0.121 inches for precise dimensional reference
• Conforms to ASME standards for gage block dimensional and tolerance requirements
• Includes Certificate of Inspection for measurement traceability documentation
• Sold individually, allowing targeted stack builds without purchasing full sets

Compatibility

Designed as an OEM-style precision reference standard compatible with standard gage block accessories including holders, wringing films, and protective cases sized for square-format steel gage blocks.

Installation Notes

Gage blocks should be handled by qualified metrologists or precision measurement technicians familiar with proper wringing, storage, and cleaning procedures. Always allow the block to thermally stabilize to the measurement environment before use, as temperature variation directly affects dimensional accuracy. Protect the lapped surfaces from contact with abrasive materials, moisture, and bare hands to prevent corrosion and surface degradation. Store in a protective case when not in use.
