Vermont Gage 112113020 Class Zz Plus Plug Gage 13.02 Mm

Product Description

The VERMONT GAGE 112113020 is a Class ZZ Plus cylindrical plug gage used to verify bore diameters to tight tolerances in a Go inspection application. The gage measures 13.02 mm in diameter with a tolerance of 0.00508 mm, providing reliable pass/fail determination for machined holes and bored features. The tool steel construction resists wear during repetitive inspection cycles. Each unit ships with a Certificate of Accuracy traceable to NIST, satisfying documentation requirements for quality systems operating under ISO or similar standards. Machinists, toolroom technicians, and quality inspectors are the primary users of this gage in production and inspection environments.

This plug gage is suited for Go inspection of through-holes and blind bores in manufacturing and metrology settings. It is also used to set and verify micrometers, verniers, and other measuring devices where a known reference diameter is required. The 13.02 mm size places it in a common range for metric-spec components found in light industrial, automotive, and precision fabrication applications. With an overall length of 2.0000 inches, the gage fits standard handle systems used across most toolroom setups. It is appropriate for both production-floor spot checks and formal inspection station use.

Key Features

• Class ZZ Plus tolerance of 0.00508 mm for precise Go inspection
• 13.02 mm diameter in tool steel for durability across repeated use cycles
• 10 microfinish surface coating reduces wear and maintains dimensional integrity
• Includes Certificate of Accuracy with NIST traceability for documented quality compliance
• Conforms to ASME B89.1 standard for plain gages
• Compatible with standard plug gage handles for easy integration into existing toolroom setups

Compatibility

Designed for use with standard plug gage handle systems. Also used to set and verify micrometers, verniers, and other measuring devices requiring a traceable reference diameter.

Installation Notes

Plug gages should be handled and stored with care to avoid contact damage to the gaging surface. Before use, clean the gage and bore with a lint-free cloth to remove chips, coolant, or debris that could affect the reading. Apply a light film of gage oil when the gage will be stored for extended periods. Inspection work of this type is typically performed by a qualified machinist or quality technician following applicable shop standards and ASME B89.1 guidelines.
