Mitutoyo 611169-531 Steel Gage Block 0.129 in Grade 0

Product Description

The MITUTOYO 611169-531 is a rectangular steel gage block measuring 0.129 inches, manufactured to Grade 0 accuracy and conforming to ASME standards. Gage blocks are precision reference standards used to calibrate measuring instruments, set comparators, and verify dimensional tolerances in metrology and quality control environments. Grade 0 denotes a high-accuracy tolerance class suitable for inspection-grade applications. Each block ships with a Certificate of Inspection, providing documented traceability. Machinists, calibration technicians, and quality engineers rely on these blocks as primary dimensional references in tool rooms, inspection labs, and manufacturing facilities.

This gage block is suited for use in inspection rooms and production environments where precise linear measurement references are required. Typical applications include setting dial indicators, height gages, and snap gages, as well as verifying the accuracy of measuring equipment. The 0.129-inch nominal size fits into standard gage block sets or can be used as a standalone reference block. Its steel construction provides durability and dimensional stability under normal shop and lab conditions.

Key Features

• Grade 0 accuracy class per ASME standards for inspection-grade dimensional reference
• 0.129-inch nominal size for precise linear calibration and measurement setup
• Steel construction provides long-term dimensional stability
• Includes Certificate of Inspection for documented traceability
• Rectangular form compatible with standard gage block accessories and holders

Compatibility

Designed as an OEM-style individual gage block for use in standard rectangular gage block sets and compatible with conventional gage block holders, wring fixtures, and accessories sized for rectangular blocks.

Installation Notes

Gage blocks are handled and serviced by calibration technicians and metrology professionals. Store blocks in their protective case and apply a light coat of anti-corrosion oil when not in use to prevent surface degradation. Clean contact surfaces with lint-free cloths and approved solvents before wringing or use. Follow your facility's calibration interval and handling procedures to maintain accuracy and traceability.
