Mitutoyo 614105-531 Square Steel Gage Block 0.05 in Grade 0

Product Description

The MITUTOYO 614105-531 is a square steel gage block with a nominal size of 0.05 inches, manufactured to Grade 0 accuracy. Gage blocks are high-precision length standards used to calibrate measuring instruments, set up comparators, and verify dimensional tolerances in machining and inspection environments. This block is constructed from steel and includes a Certificate of Inspection, confirming that it meets ASME standards for Grade 0 accuracy. Grade 0 blocks are suited for calibration lab use and precision inspection work where tight measurement uncertainty is required. Metrology technicians, quality control inspectors, and toolroom machinists are the primary users.

This gage block is intended for use in dimensional metrology applications including instrument calibration, precision layout, and gauge verification. Its 0.05-inch nominal length makes it a useful building block in block sets or as a standalone reference standard for small-dimension inspection tasks. It is appropriate for both shop-floor and laboratory environments that require ASME-compliant reference standards.

Key Features

• Grade 0 accuracy per ASME standards — suitable for calibration and high-precision inspection
• Square steel construction for durability and wringing compatibility
• Nominal size of 0.05 inches for small-dimension reference applications
• Includes Certificate of Inspection for traceability documentation
• Individual block packaging supports single-piece use or set supplementation

Compatibility

Designed as an ASME-compliant Grade 0 steel gage block for use in standard metrology and calibration applications requiring a 0.05-inch reference standard.

Installation Notes

Gage blocks are precision instruments — handle with clean, dry hands or lint-free gloves to prevent corrosion and surface contamination. Wring blocks together on a clean, flat surface using light pressure and a sliding motion; never force or drop blocks together. Store blocks in their protective case when not in use and keep them away from magnetic fields, abrasive surfaces, and temperature extremes. Calibration and inspection work should be performed by qualified metrology or quality assurance personnel.
