Precision Granite Surface Plates
Starrett granite surface plates are fabricated at the Tru-Stone Technologies Division in Waite Park, MN.
Our granite surface plates are:
Meet or exceed Federal Specification GGG-P-463c requirements
Provided with NIST Traceable calibration certificates. A2LA Accredited calibrations are available upon request. Long form, graphed reports of the inspection surface of the granite plate are also available upon request for an additional charge.
Available in Grades AA (Laboratory), A (Inspection) or B (Shop or Toolroom grade).
Available in Crystal Pink or Superior Black Granite.
Produced to support 50-lbs per square foot loading, loaded in the center of the plate.
This means that the designated load may be placed in the center of the plate without deflecting the overall accuracy more than 50%.
