Vermont Gage 112111960 Class Zz Plus Plug Gage 11.96mm

Product Description

The VERMONT GAGE 112111960 is a Class ZZ Plus plug gage ground to a nominal diameter of 11.96 millimeters with a tolerance of 0.00508 mm. It is manufactured from tool steel and features a 10 microfinish surface coating for consistent, repeatable contact. This gage is used to verify bore and hole dimensions in a go-inspection workflow. Each unit ships with a Certificate of Accuracy traceable to NIST, making it suitable for documented quality control environments. Machinists, quality technicians, and tool room personnel are the primary users of this type of precision measurement instrument.

This plug gage is designed for go inspection applications where a known-diameter reference is required to confirm that a bore or hole meets minimum dimensional acceptance criteria. It is also used to set and verify micrometers, verniers, and other measuring devices that require a traceable reference standard. The 2.0-inch overall length fits standard gage handle configurations commonly found in machine shops and inspection departments handling metric-dimensioned workpieces in the 11 mm to 12 mm bore range.

Key Features

• Class ZZ Plus tolerance grade with 0.00508 mm tolerance for precise go-inspection work
• Tool steel construction for wear resistance and dimensional stability
• 10 microfinish surface coating ensures consistent gage-to-bore contact
• Complies with ASME B89.1 dimensional metrology standards
• Includes Certificate of Accuracy with NIST traceability for documented QC use
• 2.0-inch overall length compatible with standard plug gage handles

Compatibility

Designed for use with standard plug gage handles and setting fixtures that accept a 11.96 mm diameter gage member. Also suitable for setting micrometers, verniers, and other measuring devices requiring a NIST-traceable metric reference standard.

Installation Notes

Plug gages are handled and used by quality technicians and machinists and do not require power tools or electrical connections. Keep the gage surface clean and lightly oiled when not in use to prevent corrosion and dimensional drift. Do not force the gage into an undersized bore, as this can damage the gage surface and invalidate the accuracy certificate. Store in a protective case away from temperature extremes to maintain dimensional stability.
