The inspection certificate specifies the deviation of each individual block from its nominal length. Gage blocks are commonly used to calibrate fixtures and precision instruments in workshop, inspection, and dimensional metrology applications, to inspect tools such as mounting tools, cutters, fixtures, and mechanical parts, and in the gage manufacturing process itself. Grade B gage blocks are commonly used in workshops for calibrating and inspecting mounting tools and cutters
