Dasqua 9211-3005 00 Precision Granite Square Grade, 250 x 160 x 40mm
Dasqua precision granite square squareness is +/-.0.0002mm; Squares are made from a solid block of granite that has been carefully machined to ensure accurate right angles
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
Specifically for checking the squareness (90 degree angle) between 2 surfaces or edges; Check the 90 degree squareness of X & Y axes in its horizontal position; Check the perpendicularity of the Z axes in its vertical position
Used with other tools to verify the squareness of various components & assemblies. Particularly useful where high accuracy & reliability in squareness measurements are required
This 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)
