Vermont Gage 111103000 Class Zz Plus Plug Gage 0.03 in

Product Description

The VERMONT GAGE 111103000 is a Class ZZ Plus plug gage used to verify bore diameters with high dimensional accuracy. It measures a nominal diameter of 0.03 inches with a tolerance of 0.0002 inches, making it suitable for close-tolerance inspection work. The gage is manufactured from tool steel and features a 10 microfinish surface, which supports consistent, repeatable contact with the workpiece. Each unit ships with a Certificate of Accuracy traceable to NIST standards, satisfying documentation requirements for quality management systems. Machinists, toolroom technicians, and quality inspectors use this gage in production and inspection environments where verified dimensional conformance is required.

This plug gage is used in go inspection applications to confirm that a bore or hole meets its minimum size requirement. It is also used to set and calibrate micrometers, verniers, and other measuring devices requiring a known reference diameter. At 0.03 inches, this gage addresses small-diameter inspection needs common in precision machining, instrument manufacturing, and tight-tolerance component production. Its compact overall length of 2.0 inches suits bench inspection setups and close-quarters gauge use.

Key Features

• Class ZZ Plus tolerance grade with 0.0002 inch tolerance for precise dimensional verification
• 0.03 inch nominal diameter for small-bore go inspection
• Tool steel construction for durability and wear resistance in production environments
• 10 microfinish surface finish for consistent gage contact and reduced measurement variability
• Includes Certificate of Accuracy with NIST traceability for compliance and documentation purposes
• Meets ASME B89.1 standards

Compatibility

Designed for go inspection of bores and holes at 0.03 inches nominal diameter, and for use as a setting reference with micrometers, verniers, and other measuring devices as stated by the manufacturer.

Installation Notes

This gage is handled and used by quality technicians and toolroom personnel, not installed into a system. Store the gage in its protective case when not in use to prevent damage to the lapped surface finish. Clean the gage and the workpiece bore before use to avoid measurement errors caused by debris or oil film. Do not force the gage into an undersized bore, as this can damage both the gage and the workpiece surface.
