For over 50 years, ICC has specialized in manufacturing chrome plated gage blocks. The exceptional value of these blocks is that they will out wear steel blocks 5:1. The gaging surfaces are hard chromed for wear purposes and the non-gaging surfaces are flash chromed to make the blocks corrosion free. Our gage blocks are manufactured in rectangular or square, available in complete sets or can be purchased individually as replacement blocks. We offer calibration services for gage blocks. Our management system operates in accordance with ISO/IEC 17025. Calibration certificates are available for all gage blocks ordered and are traceable to NIST.
