Mitutoyo 611635-531 Steel Gage Block 25 Mm Grade 0

Product Description

The MITUTOYO 611635-531 is a rectangular steel gage block manufactured to Grade 0 accuracy and intended for precision dimensional measurement and calibration work. Gage blocks serve as physical length standards used to calibrate measuring instruments, set comparators, and verify part dimensions on the shop floor or in a metrology lab. This block measures 25 mm in overall length and is supplied with a Certificate of Inspection confirming it meets the stated accuracy grade. Grade 0 blocks fall within the tighter tolerance band of the ASME gage block standard, making them appropriate for inspection and calibration environments rather than general production use.

This gage block is suited for metrology labs, quality control departments, and tool rooms where traceable dimensional standards are required. Typical applications include calibrating micrometers, vernier calipers, and height gages, as well as setting up comparator stands for go/no-go inspection work. It is used by calibration technicians, quality engineers, and precision machinists working in both production and inspection settings.

Key Features

• Grade 0 accuracy per ASME standards, suitable for inspection and calibration use
• Steel construction provides durability and wear resistance for repeated wringing and handling
• 25 mm nominal length covers a common reference dimension in metric measurement setups
• Includes Certificate of Inspection for traceability documentation
• Rectangular form allows wringing to other blocks for building up composite dimensions

Compatibility

Designed as an OEM-style precision gage block for use in metric dimensional calibration and inspection setups conforming to ASME gage block standards.

Installation Notes

Gage blocks are handled and stored by calibration technicians and quality control personnel. Clean all mating surfaces with a lint-free cloth before wringing blocks together to avoid contamination that can affect accuracy or damage surfaces. Store blocks in their protective case when not in use to prevent corrosion and mechanical damage. Do not drop or impact blocks, as this can alter their calibrated dimensions.
