Vermont Gage 112301330 Class Zz Plus Plug Gage 1.33mm

Product Description

The VERMONT GAGE 112301330 is a Class ZZ Plus plug gage designed for precision dimensional inspection of small bores and holes. Built from tool steel with a 10 microfinish surface, this plug gage measures internal diameters at 1.33 mm with a tolerance of 0.00508 mm, providing reliable Go inspection performance. Each unit ships with a Certificate of Accuracy traceable to NIST, confirming the gage meets ASME B89.1 standards. It is used by machinists, quality technicians, and metrologists who need repeatable, traceable measurement in a compact, durable gage body. Overall length is 2.0000 inches.

This plug gage is suited for Go inspection tasks in manufacturing and quality control environments. It is commonly used to verify bore diameters in machined parts and is also appropriate for setting and verifying micrometers, verniers, and other measuring devices. The 1.33 mm diameter makes it appropriate for small-bore applications where precision tolerances are critical. Typical users include machinists, inspection technicians, and tool room professionals working in both production and prototype settings.

Key Features

• Tool steel construction for durability and wear resistance in daily inspection use
• Includes Certificate of Accuracy with NIST traceability
• Meets ASME B89.1 standards for dimensional gaging
• Overall length of 2.0000 inches in a compact, easy-to-handle form factor

Compatibility

Designed for Go inspection of 1.33 mm diameter bores, and for use in setting micrometers, verniers, and other measuring devices requiring a traceable reference standard.

Installation Notes

Plug gages are handled and applied by quality technicians or machinists during inspection procedures. Clean both the gage pin and the bore being checked before use to prevent false readings caused by debris or contamination. Do not force the gage into an undersized bore, as this can damage the gage surface and compromise accuracy. Store in a protective case when not in use to maintain the 10 microfinish surface condition.
