Mitutoyo 611615-531 Steel Gage Block 5 Mm Grade 0

Product Description

The MITUTOYO 611615-531 is a rectangular steel gage block with a nominal length of 5 mm, manufactured to Grade 0 accuracy. Gage blocks serve as dimensional reference standards used to calibrate measuring instruments, set comparators, and verify part tolerances on the shop floor or in a metrology lab. This block is supplied with a Certificate of Inspection, confirming that it meets Grade 0 tolerances as defined by ASME standards. The steel construction provides the dimensional stability and hardness required for repeated use in precision measurement applications. Grade 0 is appropriate for calibration and inspection work where tight dimensional accuracy is required.

This gage block is suited for use in tool rooms, quality control labs, and production environments where reference-grade dimensional standards are required. It is used by machinists, metrologists, quality technicians, and calibration specialists to set and verify measuring tools such as micrometers, verniers, and height gages. Its rectangular form is compatible with standard gage block accessory sets and wringing procedures used in everyday metrology workflows.

Key Features

• Grade 0 accuracy per ASME standards, suitable for calibration and inspection use
• Nominal length of 5 mm in a rectangular block form
• Steel construction for dimensional stability and surface hardness
• Includes Certificate of Inspection for traceability documentation
• Individual block packaging for replacement or supplemental use

Compatibility

Designed as an OEM-style rectangular gage block for use with standard gage block accessory sets and wringing stack-ups in precision metrology applications.

Installation Notes

Gage blocks are handled and serviced by metrologists and precision measurement technicians. Before use, blocks should be cleaned of protective oil and allowed to thermally stabilize to the ambient measurement environment, typically 68 degrees F per ASME B89 guidelines. Avoid dropping or contacting the lapped measuring faces with abrasive surfaces. Store in a protective case when not in use to prevent corrosion and surface damage.
