Vermont Gage 111316450 Class Zz Plus Plug Gage 0.1645 in

Product Description

The VERMONT GAGE 111316450 is a Class ZZ Plus plug gage designed for precision go inspection of hole diameters at 0.1645 inches. Manufactured from tool steel and finished to a 10 microfinish surface, this gage provides a tolerance of 0.0002 inches, making it suitable for verifying tight-tolerance bores in production and inspection environments. It ships with a Certificate of Accuracy traceable to NIST, confirming dimensional compliance to ASME B89.1. Licensed metrology technicians, machinists, and quality control inspectors rely on this class of gage for repeatable, traceable measurement results.

This plug gage is used wherever precise go inspection of a 0.1645-inch diameter hole is required. Typical applications include incoming inspection, in-process quality checks, and calibration of micrometers, verniers, and other measuring devices. It suits both production floor and metrology lab environments in aerospace, automotive, medical device, and general manufacturing settings. The overall length of 2.0 inches allows easy single-hand handling and consistent insertion into shallow or moderate-depth bores.

Key Features

• Class ZZ Plus tolerance of 0.0002 inches for precise go inspection
• Tool steel construction for hardness and long service life
• 10 microfinish surface for smooth, repeatable gage entry
• Includes Certificate of Accuracy with NIST traceability
• Conforms to ASME B89.1 dimensional standards
• Compact 2.0-inch overall length for easy handling in confined inspection areas

Compatibility

Designed as a go inspection gage for 0.1645-inch diameter holes and as a setting reference for micrometers, verniers, and other measuring devices where a traceable, known-diameter standard is required.

Installation Notes

Plug gages are handled and used by metrology technicians, machinists, or quality inspectors — no permanent installation is required. Clean the gage and the bore with a lint-free cloth before use to prevent debris from affecting measurement accuracy. Never force the gage into a bore; go gages should pass under light hand pressure only. Store in a protective case away from moisture and extreme temperature swings to preserve dimensional stability.
