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)
