About the Starrett Crystal Pink Granite Surface Plate — Grade A
Grade A (0.000050"/6" tolerance) is Starrett's inspection-grade specification, the most commonly specified granite plate grade for quality-control departments and calibration labs performing everyday inspection rather than reference-standard work.
Available across the full Starrett size range, Grade A plates balance accuracy against cost for facilities that don't need a Grade AA master reference.
