Mitutoyo 614117-531 Square Steel Gage Block 0.17 in Grade 0

Product Description

The MITUTOYO 614117-531 is a square steel gage block measuring 0.17 inches, manufactured to Grade 0 accuracy. Gage blocks serve as precision length references used to calibrate measuring instruments, set comparators, and verify dimensional tolerances on the shop floor or in the metrology lab. This block conforms to ASME standards and includes a Certificate of Inspection, confirming it has been measured and documented against traceable reference standards. Grade 0 designation indicates a high level of dimensional accuracy, making this block appropriate for applications that require tighter calibration reference tolerances than general-purpose Grade 1 or Grade 2 blocks.

This gage block is suited for use in tool rooms, quality control labs, and precision machining environments. Machinists, metrologists, and quality technicians use blocks like this one to establish reference lengths, set up height gages, and calibrate micrometers or calipers. The square geometry allows it to be wrung with other blocks in a set to build up a target measurement. It is a single-block unit sold individually, appropriate as a replacement for a lost or damaged block or as a standalone reference standard.

Key Features

• Grade 0 accuracy per ASME standards, suitable for precision calibration reference use
• Steel construction provides durability and wear resistance for repeated wringing and handling
• Square form factor allows wringing with other compatible gage blocks to build composite lengths
• Includes Certificate of Inspection for traceability documentation
• Nominal length of 0.17 inches verified to ASME specification tolerances

Compatibility

Designed as a standalone square steel gage block conforming to ASME standards, compatible with other square gage blocks of the same geometry for wringing into block stacks.

Installation Notes

Gage blocks are handled and wrung by metrology technicians and precision machinists, not installed in a mechanical system. Store blocks in their protective case when not in use to prevent corrosion and surface damage. Clean contact surfaces with a lint-free cloth and appropriate gage block cleaning solution before wringing. Apply a light film of gage block oil or anti-corrosion compound for long-term storage.
