Mitutoyo 611204-531 Steel Gage Block 4 in Grade 0

Product Description

The MITUTOYO 611204-531 is a rectangular steel gage block manufactured to Grade 0 accuracy and conforming to ASME standards. Gage blocks are precision reference standards used to calibrate measuring instruments, verify dimensional accuracy, and set up comparators and surface plates. This block measures 4 inches in nominal length and is supplied with a Certificate of Inspection, making it suitable for use in metrology labs, machine shops, and quality control environments. Grade 0 indicates a high level of dimensional accuracy and surface finish, placing it in a class appropriate for demanding inspection and calibration work. Installation and use is performed by metrologists, machinists, and quality technicians.

This gage block is intended for use as a precision length reference in dimensional metrology applications. It is appropriate for laboratory calibration environments as well as shop-floor inspection stations where traceable length standards are required. The Grade 0 accuracy classification makes it well suited for setting comparators, calibrating micrometers and calipers, and verifying precision fixtures. It is packaged individually and ships as a single unit.

Key Features

• Grade 0 accuracy classification per ASME standards for high-precision metrology
• Nominal length of 4 inches for use as a traceable dimensional reference
• Rectangular geometry compatible with standard gage block wringing and stacking
• Steel construction for durability and dimensional stability
• Includes Certificate of Inspection for traceability documentation
• Conforms to ASME standards

Compatibility

Designed as an OEM-style precision reference block for use with standard gage block accessories, holders, and comparator setups requiring a 4-inch steel reference standard.

Installation Notes

Gage blocks are handled and used by metrologists and precision measurement technicians. Prior to use, clean block surfaces with an appropriate solvent to remove protective coating or contaminants. Handle with lint-free gloves to prevent corrosion from skin oils. Store in the supplied case or protective packaging when not in use to maintain surface integrity and dimensional stability.
