Mitutoyo 611204-541 4 in. Rectangular Steel AS-1 Gage Block

Rectangular Steel AS-1 Gage Block The Mitutoyo grade AS-2 rectangular gage block is made of steel has a nominal length engraved in inches and is supplied with a Mitutoyo inspection certificate that states that the block meets American Society of Mechanical Engineers (ASME) B89.1.9-2002 grade standard for flatness length parallelism and surface finish. The inspection certificate specifies the deviation of the 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. This grade AS-2 gage block is commonly used in workshops for calibrating and inspecting mounting tools and cutters. It is made of high-carbon high-chrome steel which has a high hardness for minimum deterioration and is selected for its wear-resistance. This gage block has a rectangular base for accurate wringing. Nominal length is measured in inches and indicated with laser-etched black characters. The length of a gage block is usually slightly shorter than its stamped nominal length to account for the thin layer of oil or wring film used when two or more blocks are wrung together. An identification number is laser-etched on the block for traceability.
