Mitutoyo 611144-541 Steel Gage Block 0.104 in Grade AS-1

Product Description

The MITUTOYO 611144-541 is a rectangular steel gage block ground to a nominal size of 0.104 inches and certified to ASME Grade AS-1 accuracy. Gage blocks at this grade are used as dimensional reference standards in calibration labs, toolrooms, and quality control environments where precise length verification is required. A Certificate of Inspection is included, confirming the block has been measured and documented against traceable standards. Licensed metrologists, machinist toolroom technicians, and quality assurance inspectors are the primary users of this type of precision reference standard.

This gage block is suited for both shop-floor and laboratory measurement applications where a reliable, single-size reference is needed. It can be used as a standalone reference or wrung with other blocks in a set to build up a required measurement stack. Typical applications include machine tool setup, fixture verification, comparator calibration, and inspection of precision-machined components in manufacturing environments.

Key Features

• Nominal size of 0.104 inches ground to ASME Grade AS-1 tolerance
• Steel construction for durability and dimensional stability
• Rectangular geometry compatible with standard wring stacking practices
• Includes Certificate of Inspection for traceability documentation
• Conforms to ASME standards for gage block accuracy

Compatibility

Designed as a single-size rectangular steel gage block conforming to ASME Grade AS-1 specifications, suitable for use with standard gage block accessories and holders in toolroom and metrology laboratory settings.

Installation Notes

Gage blocks should be handled by metrology technicians or qualified toolroom personnel using clean, lint-free gloves to prevent corrosion from skin contact. Before use, blocks should be temperature-stabilized in the measurement environment, typically to 68 degrees F (20 degrees C) as specified by ASME standards. Clean and lightly oil the measuring faces before storage to prevent oxidation. Do not drop or stack improperly, as impact damage or burring of the lapped faces will compromise accuracy.
