Mitutoyo 614204-541 4 in. Square Steel AS-1 Gage Block

Square Steel AS-1 Gage Block

The Mitutoyo grade AS-1 square gage block is made of steel, has its 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-1 gage block is commonly used for workshop and inspection applications to calibrate fixtures and precision instruments, to inspect a variety of tools such as mounting tools, cutters, fixtures, and mechanical parts, and for gage manufacturing applications. 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 square base for accurate wringing, to attain a height reference standard, and for the ability to make a dedicated inspection jig. 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. The block has a depth of 0.95 inches.
