Vermont Gage 111182300 Class Zz Plus Plug Gage 0.823 in

Product Description

The VERMONT GAGE 111182300 is a Class ZZ Plus plug gage designed for dimensional go inspection of bored, reamed, and machined holes. Built from tool steel with a 10 microfinish surface, this gage measures a nominal diameter of 0.823 inches with a tolerance of 0.0002 inches. It ships with a Certificate of Accuracy with NIST traceability, confirming compliance with ASME B89.1 standards. Machinists, quality technicians, and metrology professionals use this gage to verify that a hole falls within the acceptable dimensional range before a part advances to the next stage of production or assembly.

This plug gage is suited for use in production inspection environments, tool rooms, and quality labs. It is commonly used alongside set micrometers, verniers, and other precision measuring devices to establish or confirm calibration references. With an overall length of 2.0 inches, the 111182300 fits comfortably in hand for repetitive pass-fail checks on small-to-medium bore sizes in both prototype and high-volume manufacturing settings.

• Tool steel construction for wear resistance and dimensional stability
• Includes Certificate of Accuracy with NIST traceability
• Meets ASME B89.1 dimensional gage standards
• Overall length of 2.0 inches for ergonomic single-hand use

Compatibility

Designed as an OEM-style go plug gage for use with set micrometers, verniers, and other precision measuring devices requiring a 0.823-inch reference diameter per ASME B89.1.

Installation Notes

Plug gages are handled and stored by metrology and quality personnel, not installed in a mechanical system. Clean the gage and bore surfaces before use to prevent debris from affecting readings or causing premature wear. Store the gage in its protective case when not in use to preserve the precision ground surface and prevent corrosion. Handle with clean, dry hands or lint-free gloves to avoid contamination that could affect dimensional accuracy.
