Vermont Gage 111303550 Class Zz Plus Plug Gage 0.0355 in

Product Description

The VERMONT GAGE 111303550 is a Class ZZ Plus plug gage machined from tool steel and used to verify bore and hole dimensions to tight tolerances. It measures a diameter of 0.0355 inches with a tolerance of 0.0002 inches, making it well-suited for high-precision go inspection tasks. The gage carries a 10 microfinish surface rating, which reduces wear and delivers consistent contact across repeated checks. A Certificate of Accuracy with NIST traceability is included, supporting quality-system documentation requirements. Metrology technicians, toolroom machinists, and quality control inspectors rely on plug gages of this class for reliable pass/fail determination in production and inspection environments.

This plug gage is designed for use in go inspection applications where dimensional conformance of small-diameter bores must be confirmed quickly and repeatedly. It is also appropriate for setting and verifying micrometers, verniers, and other precision measuring devices. At 0.0355 inches in diameter, this gage addresses the small-hole end of the measurement range and is commonly used in precision machining shops, aerospace component inspection, and tight-tolerance manufacturing lines where ASME B89.1 standards govern dimensional verification.

Key Features

• Class ZZ Plus tolerance rating provides a tighter accuracy grade suitable for go inspection
• 0.0355-inch measurement diameter with 0.0002-inch tolerance for precise bore verification
• 10 microfinish surface finish reduces wear and ensures repeatable gage contact
• Tool steel construction for durability under regular inspection-floor use
• Includes Certificate of Accuracy with NIST traceability to support ISO and quality documentation
• Conforms to ASME B89.1 standards for plain gage dimensional requirements

Compatibility

Designed for go inspection of bores and holes at 0.0355 inches diameter and for use as a setting standard with micrometers, verniers, and other precision measuring devices.

Installation Notes

Plug gages are handled and used by metrology technicians and quality inspectors rather than installed in a mechanical system. Clean the gage and the bore or measuring device contact surfaces before each use to prevent debris from affecting readings. Store the gage in its protective case when not in use to prevent corrosion and surface damage to the tool steel. Follow shop calibration intervals and handle with care to avoid dropping, which can alter the gage geometry and invalidate NIST traceability.
