An alloy gauge block set is a collection of precision-machined blocks made from high-quality alloy materials,
used as length standards for calibrating and setting measuring equipment like micrometers, calipers, and other
precision tools. These blocks, also known as Johansson blocks or slip gauges, are highly accurate in terms of
dimensional stability and are commonly used in machining, manufacturing, and metrology labs.

A steel gauge block set is a precision tool used for calibration and measurement in industrial, manufacturing,
and laboratory settings. Also known as Johansson blocks or slip gauges, gauge blocks are rectangular or square
pieces of steel (or other materials) that have been ground and lapped to a precise thickness. They are primarily
used to calibrate or verify the accuracy of other measuring instruments, set up machine tools, and establish
exact measurements for machining processes.

Applications:

• Machining and Tooling: Used in machine shops to ensure
  the precision setup of equipment.


• Inspection and Calibration: Employed in metrology labs
  to verify the accuracy of various measurement tools.


• Precision Manufacturing: Ensures parts and tools meet exact
  dimensional specifications for industries like aerospace, automotive, and electronics.

An alloy gauge block set is an essential tool for ensuring high
levels of measurement precision, making it indispensable in environments where accuracy
is critical.
