ITEM #: 5304392
Grade AA (Laboratory Grade) granite tri-squares have three sides and are used to check the X, Y, Z axes on CNC machine tools and coordinate measuring machines (CMM). When used in a horizontal position, they can check the X and Y axes for 90° squareness. When used in a vertical position, they can be traced along the edge to check the perpendicularity of the Z axis. They are also used for checking general squareness and straightness. They are durable, corrosion-resistant, and tolerate temperature...

When used in a vertical position, they can be traced along the edge to check the perpendicularity of the Z axis. They are also used for checking general squareness and straightness. They are durable, corrosion-resistant, and tolerate temperature fluctuations. These grade AA tri-squares have the highest degree of accuracy and are often used in calibration laboratories and high-precision metrology and inspection labs.
