HHIP 4901-0602 4" X 3" Machinist Steel Square

HHIP 10 X 6 X 1 Precision Granite Square Squareness is +/-.0.0002. Black granite squares are more durable than pink granite and help to avoid scratching. A precision granite square is a tool used specifically for checking the squareness (90-degree angle) between two surfaces or edges. Check 90 degree squareness of the X and Y axes when used in it's horizontal position. They are particularly useful in applications where high accuracy and reliability in squareness measurements are required, such as in precision machining and tooling. An inspection certificate from the manufacturer is provided. Check 90 degree squareness of the X & Y axes when in it's horizontal position. Check perpendicularity of the Z axes when in it's vertical position. Granite squares are often used with other measuring tools to verify the squareness of components & assemblies. They are used in applications where high accuracy & reliability in squareness measurements are required like in precision machining & tooling. Squareness is +/-.0.0002. An inspection certificate from the manufacturer is provided (Not NIST Traceable).
