Vermont Gage 111332950 Class Zz Plus Plug Gage 0.3295 in

Product Description

The VERMONT GAGE 111332950 is a Class ZZ Plus cylindrical plug gage used to verify bore and hole diameters to a high degree of precision. Manufactured from tool steel, it measures a nominal diameter of 0.3295 inches with a tolerance of 0.0002 inches. The working surface carries a 10 microfinish, which supports accurate, repeatable contact during go inspection. Each unit ships with a Certificate of Accuracy traceable to NIST, making it suitable for use in calibrated inspection environments. This gage is installed and used by quality control technicians, machinists, and metrologists working to ASME B89.1 dimensional standards.

This plug gage is designed for go inspection applications where a controlled diameter must be confirmed within tight tolerance bands. It is also used alongside set micrometers, verniers, and other measuring devices as a reference standard for zeroing or verifying instrument calibration. Typical use environments include machine shops, manufacturing inspection lines, and metrology labs where dimensional verification of drilled, reamed, or bored features is required on a routine basis.

Key Features

• Class ZZ Plus tolerance grade at 0.0002 inches for high-precision go inspection
• 10 microfinish working surface for consistent, low-distortion contact
• Tool steel construction for wear resistance and dimensional stability
• Certificate of Accuracy with NIST traceability included
• Conforms to ASME B89.1 dimensional gage standards
• Overall length of 2.0 inches for convenient handheld use

Compatibility

Designed for go inspection of holes and bores at 0.3295 inches nominal diameter, and for use as a reference standard with set micrometers, verniers, and other calibrated measuring devices.

Installation Notes

This gage is handled and used by trained inspection or metrology personnel, not installed in a mechanical system. Before use, clean the gage and the workpiece bore with a lint-free cloth to remove debris or oils that could affect the measurement. Apply only light, consistent hand pressure when inserting the plug into the bore to avoid false readings or surface damage. Store in a protective case when not in use to maintain surface finish and dimensional integrity.
