Vermont Gage 111133100 Class Zz Plus Plug Gage 0.331 in

Product Description

The VERMONT GAGE 111133100 is a Class ZZ Plus plug gage designed for precise go inspection of bored holes, drilled passages, and machined features. It measures a nominal diameter of 0.331 inches with a tolerance of 0.0002 inches, making it suited for applications where tight dimensional verification is required. Manufactured from tool steel and finished to a 10 microfinish surface quality, this plug gage delivers consistent, repeatable results. Each unit ships with a Certificate of Accuracy traceable to NIST, supporting quality documentation requirements in production and inspection environments. Machinists, quality technicians, and tool-and-die professionals use this gage as part of standard dimensional inspection routines.

This plug gage is used in shop-floor and lab inspection settings wherever a 0.331 inch diameter feature must be verified against tolerance. It is appropriate for use with go inspection procedures, setting micrometers, vernier calipers, and other measuring devices per standard metrology workflows. Suitable for both production line inspection and incoming-goods verification in manufacturing facilities, machine shops, and precision fabrication environments. The compact overall length of 2.0 inches allows use in confined or staged inspection fixtures.

Key Features

• Class ZZ Plus tolerance grade with 0.0002 inch accuracy for precise go inspection
• 10 microfinish surface finish for consistent gage contact and minimal wear on mating features
• Tool steel construction for durability in production inspection environments
• Includes Certificate of Accuracy with NIST traceability for quality system documentation
• Conforms to ASME B89.1 standards for dimensional measurement tools
• Compact 2.0 inch overall length suited for bench and fixture use

Compatibility

Designed for go inspection of machined features with a nominal diameter of 0.331 inches. Compatible with standard plug gage handles and gage-block inspection setups. Also specified for use with set micrometers, verniers, and other measuring devices requiring a precise reference diameter.

Installation Notes

Plug gages are handled and stored by metrology or quality technicians following standard gage calibration and care procedures. Keep the gage clean and lightly oiled when not in use to prevent corrosion of the tool steel surface. Do not force the gage into a feature; enter at the centerline axis with light, steady pressure to avoid false readings or gage wear. Store in a protective case away from direct contact with other metal tooling to maintain the 10 microfinish surface integrity.
