Precision gauge block for calibration
The Mitutoyo 611202-541 is a rectangular steel gauge block manufactured to ASME AS-1 grade. It serves metrology labs and quality-control teams that require a traceable 2 in reference standard for calibrating micrometers and other measuring instruments.
Fits into inspection workflows
The block’s 1 3/8 in face length and 23/64 in face width allow secure wringing to adjacent blocks without a clamping hole. Its Grade AS-1 tolerance of -0.0120 in to 0 in on length and -0.0080 in to -0.0020 in on width supports direct verification of instrument accuracy.
Replaces worn or lower-grade references
Upgrading from Grade AS-2 or uncertified blocks is justified when calibration procedures demand ASME AS-1 uncertainty limits. The included Certificate of Inspection satisfies audit requirements that a Long Form Calibration Certificate would not.

Questions about this item
How much can the 2 in length shrink before the Grade AS-1 tolerance is exceeded?
The length tolerance allows a maximum negative deviation of .0120 in from the nominal 2 in size.
How much heat does the steel block generate during continuous measurement work?
As a passive steel gauge block it produces no heat of its own; any temperature change comes only from the surrounding environment or handling.
What measuring instrument is needed to use this rectangular gauge block?
It is designed for use with micrometers and other precision length-measuring tools that can accept a 1 3/8 in by 23/64 in rectangular block.
