Gauge blocks are the main means of standardising lengths used in industry.Product Details:8pcs/set, ( 0 Grade/1 Grade)Size(mm):125mm 150mm 175mm 200mm250mm 300mm 400mm 500mmTips when you use them:To use them, the blocks are removed from the set, cleaned of their protective coating (petroleum jelly or oil) and screwed together to form a stack of the desired size. The blocks are calibrated accurately at 20 C (68 F) and should be kept at this temperature when measuring. This mitigates the effects of thermal expansion. Wear-resistant blocks, made of a harder substance such as tungsten carbide, are mounted at the ends of the stack wherever possible to protect the gauge block from damage during use.
