Vermont Gage 111145200 Class Zz Plus Plug Gage 0.452 in

Product Description

The VERMONT GAGE 111145200 is a Class ZZ Plus plug gage designed to measure bore and hole diameters with high accuracy. Built from tool steel and finished to a 10 microfinish surface quality, this gage delivers consistent, repeatable results in dimensional inspection applications. It measures a nominal diameter of 0.452 inches with a tolerance of 0.0002 inches, conforming to ASME B89.1 standards. Each unit ships with a Certificate of Accuracy traceable to NIST. Licensed machinists, quality technicians, and calibration professionals use this gage as part of go inspection routines to verify that manufactured parts fall within specified tolerances.

This plug gage is suited for go inspection tasks in machine shops, manufacturing facilities, and quality control environments. It is used alongside micrometers, verniers, and other precision measuring devices to confirm bore diameter acceptance. The 0.452-inch diameter and 2.0-inch overall length make it appropriate for a range of production and inspection setups where tight dimensional control is required. It is a practical tool for any environment operating under ASME B89.1 dimensional measurement protocols.

Key Features

• Class ZZ Plus tolerance rating with 0.0002-inch dimensional tolerance for high-accuracy go inspection
• 10 microfinish surface quality reduces wear on mating bores during repeated use
• Tool steel construction for durability in production inspection environments
• Conforms to ASME B89.1 standards for dimensional gage accuracy
• Includes Certificate of Accuracy with NIST traceability for documentation and audit requirements

Compatibility

Designed for go inspection use with micrometers, verniers, and other precision measuring devices where a 0.452-inch nominal bore diameter check is required, in accordance with ASME B89.1.

Installation Notes

Plug gages are handled and used by quality technicians and metrology professionals. Store the gage in its protective case when not in use to prevent surface damage and corrosion. Before use, clean the gage and the bore being inspected to remove chips, coolant, and debris that could affect measurement accuracy. Apply light gage oil when appropriate to minimize wear during repeated inspection cycles.
