Vermont Gage 111190800 Class Zz Plus Plug Gage 0.908 in

Product Description

The VERMONT GAGE 111190800 is a Class ZZ Plus plug gage designed for precise go-inspection work in dimensional quality control applications. Manufactured from tool steel, it measures a nominal diameter of 0.908 inches with a tolerance of 0.0002 inches and a surface finish of 10 microinches. The overall length is 2.0 inches. Each unit ships with a Certificate of Accuracy with NIST traceability, making it suitable for use in calibrated inspection environments where documented measurement standards are required. Machinists, quality technicians, and toolroom professionals rely on this type of gage for fast, reliable attribute inspection of bored holes and machined features.

This plug gage is used in manufacturing and toolroom settings to verify that a machined bore or hole meets minimum dimensional requirements for the go condition. Typical applications include incoming inspection, in-process quality checks, and calibration of set micrometers, verniers, and other measuring devices. Its compact size and standard handle design make it easy to integrate into existing gage setups on the shop floor or in a dedicated inspection area.

Key Features

• Nominal measurement diameter of 0.908 inches for precise go-inspection
• Tolerance of 0.0002 inches per Class ZZ Plus classification
• 10-microinch surface finish for consistent, repeatable contact
• Tool steel construction for durability in production environments
• Includes Certificate of Accuracy with NIST traceability
• Conforms to ASME B89.1 standards

Compatibility

Designed for use as a go plug gage in dimensional inspection of machined bores and holes. Also suitable for setting and verifying micrometers, verniers, and other measuring devices requiring a known reference diameter.

Installation Notes

Plug gages of this type are handled and used by quality technicians and toolroom machinists. Clean the gage and the bore being inspected before use to prevent debris from affecting measurement accuracy. Store the gage in its protective case when not in use to prevent damage to the precision-ground surface. Do not force the gage into a bore; light hand pressure is the correct technique for go-inspection use.
