Gauge Blocks
Rectangular
Square
Vital for dimensional quality control, these gauge blocks are often used for precision layout, machine setup, and producing close-tolerance dies and fixtures. All are high-carbon, high-chrome steel and have excellent stability and resistance to thermal expansion.
Gauge blocks are classified by grade based on tolerance—the smaller the tolerance, the greater the accuracy. All blocks are individually numbered for recalibration at a later date.
Size refers to the distance between the block’s two measuring surfaces. To get a size that isn’t offered, press two clean blocks together with a twisting/sliding motion.
Square blocks have a hole so they can be stacked on top of other blocks and secured with a rod (not included).

Mitutoyo Gauge Block Sets with Calibration Certificate
These sets come with a certificate of calibration traceable to NIST that states they’ve passed a test for accuracy. They’re used for precision layout, machine setup, and producing close-tolerance dies and fixtures. Blocks are high-carbon, high-chrome steel and have excellent stability and resistance to thermal expansion.
Gauge blocks are classified by grade based on tolerance—the smaller the tolerance, the greater the accuracy. All blocks are individually numbered for recalibration at a later date.
Size refers to the distance between the block’s two measuring surfaces.
