HHIP 4901-2705 10 x 6 x 1" Precision Granite Square, Black
These squares are made from a solid block of granite that has been carefully machined to ensure accurate right angles. Black granite squares are more durable than pink granite and help to avoid scratching.
Granite precision squares come with one large face and two edges that are finished flat and square to each other. It consists of two faces precisely perpendicular to each other, forming a 90-degree angle.
A granite square is used for checking the squareness (90-degree angle) between two surfaces or edges. 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". Square has a round hole so it weighs less and is easier to handle. An inspection certificate from the manufacturer is provided (Not NIST Traceable).
