Gage Blocks – Mitutoyo Gage Blocks & Sets

Explore Mitutoyo gage blocks for calibration, instrument setup and precision dimensional reference applications.

Precision Length Standards for Calibration and Setup

Mitutoyo gage blocks are precision-lapped length standards used to establish known dimensions. By wringing selected blocks together, inspectors and technicians can build a reference length for calibrating instruments, setting comparators, checking fixtures or supporting other dimensional verification tasks.

Gage blocks are available as individual blocks or coordinated sets in inch and metric sizes. Mitutoyo offers steel, ceramic and carbide options, allowing users to compare wear resistance, handling characteristics, thermal behavior and the conditions in which the blocks will be used. Their ability to wring together makes many precise reference lengths possible from one coordinated set.

Selecting and Maintaining Gage Blocks

The appropriate set depends on the required length combinations, tolerance, frequency of use and role within the quality system. Master reference blocks may have different grade and calibration requirements than working blocks used regularly on the shop floor.

• Choose inch or metric blocks to match the measurement system.
• Select an accuracy grade appropriate for calibration, inspection or setup work.
• Compare steel, ceramic and carbide based on wear, handling and environment.
• Use proper cleaning, wringing, storage and corrosion-control practices.
• Set a calibration interval based on use, risk and quality requirements.

Gage Block and Calibration Support

Florida Metrology can help identify Mitutoyo gage blocks and sets for your dimensional measurement process. Because gage blocks act as reference standards, their condition and calibration status directly affect the measurements built from them.
