Mitutoyo .1 in AS-1 Gage Block

This rectangular steel gauge block has a nominal size of 0.1 in and meets ASME AS-1 grade specifications. It is intended for calibration labs and precision machinists who require traceable length standards. The block ships with a Certificate of Inspection but no long-form calibration certificate.

Critical tolerance and grade

The deciding specification is the AS-1 grade with length tolerance of -0.0120 in to 0 in and width tolerance of -0.0080 in to -0.0020 in. Buyers needing tighter tolerances or a different grade cannot use this block. The 611191-541 model has no hole and conforms to ASME standards.

Simple handling with care

Installation means wringing the block into a stack on a clean surface plate; no tools are required. The most common issue is surface damage from debris or corrosion that invalidates the certified tolerance. Users who need a long-form calibration certificate must arrange that separately.

Questions about this item

What does the .1 in nominal size mean when I stack this block with others?

The .1 in nominal size is the exact length this block contributes to a stack; combined with other blocks it builds the precise dimension you need.

How does the ASME AS-1 grade limit the length and width variation I will see?

ASME AS-1 limits length tolerance to -.0120 in to 0 in and width tolerance to -.0080 in to -.0020 in, so the block will never exceed its nominal length and stays within those width bounds.

Will the 1 3/16 in by 23/64 in faces fit my standard gauge block holder?

The rectangular faces measure 1 3/16 in long by 23/64 in wide, matching common long-form holders that accept those dimensions.
