Vermont Gage 111150500 Class Zz Plus Plug Gage 0.505 in

Product Description

The VERMONT GAGE 111150500 is a Class ZZ Plus plug gage manufactured from tool steel, designed for precise dimensional inspection of bored, reamed, and drilled holes. It measures a nominal diameter of 0.505 inches with a tolerance of 0.0002 inches and a 10 microfinish surface finish. The gage is used to verify whether a workpiece hole falls within acceptable limits during Go inspection procedures. Each unit ships with a Certificate of Accuracy traceable to NIST, confirming compliance with ASME B89.1 standards. Machinists, quality control technicians, and tool room personnel use this gage as part of routine dimensional verification workflows.

This plug gage is suited for Go inspection applications on production and inspection floors in both light manufacturing and precision machining environments. It is also used to calibrate and verify the accuracy of setting micrometers, verniers, and other measuring devices. The 0.505-inch diameter and 2.0-inch overall length make it a compact, hand-held reference tool for high-frequency inspection tasks where consistent, repeatable measurement is required.

Key Features

• Class ZZ Plus tolerance rating with 0.0002-inch tolerance for high-precision Go inspection
• 10 microfinish surface finish reduces wear and ensures consistent gage contact
• Tool steel construction provides hardness and durability in production environments
• Includes Certificate of Accuracy with NIST traceability
• Conforms to ASME B89.1 standards
• Compact 2.0-inch overall length for easy hand-held use

Compatibility

Designed for Go inspection use with setting micrometers, verniers, and other measuring devices requiring a 0.505-inch diameter reference standard per ASME B89.1.

Installation Notes

Plug gages should be handled with clean, dry hands or cotton gloves to prevent corrosion from skin oils. Store the gage in its protective case when not in use and keep it away from abrasive surfaces. Verify the gage certificate is current before use in a calibrated inspection process. No power source or special tooling is required for use.
