Vermont Gage 111278200 Class Zz Minus Plug Pin Gage 0.782 in

Product Description

The VERMONT GAGE 111278200 is a Class ZZ minus tolerance plug pin gage with a 0.7820-inch measurement diameter. It is used to verify that a hole or bore does not exceed the maximum allowable size limit, serving as a NoGo functional inspection tool. The gage measures 2 inches in overall length and is manufactured from steel for durability in shop-floor and quality-control environments. A Certificate of Accuracy with NIST traceability is included, confirming the gage meets Class ZZ dimensional standards. Machinists, quality technicians, and inspection personnel use this tool to confirm bore tolerances during production and incoming inspection workflows.

This plug pin gage is suited for NoGo inspection tasks in manufacturing, machine shop, and metrology lab settings. It is also used for setting and verifying micrometers, verniers, and other precision measuring devices. The 0.000200-inch tolerance rating makes it appropriate for general-purpose dimensional inspection where Class ZZ accuracy is specified. Typical applications include incoming material inspection, in-process quality checks, and gauge calibration setups in both light industrial and precision machining environments.

Key Features

• Class ZZ minus tolerance rating for NoGo bore inspection
• 0.7820-inch measurement diameter with 0.000200-inch tolerance
• 2-inch overall length for easy single-hand handling
• Steel construction for wear resistance in production environments
• 10 micro surface finish coating for consistent contact and measurement accuracy
• Includes Certificate of Accuracy with NIST traceability

Compatibility

Designed for use as a NoGo inspection gage and for setting micrometers, verniers, and other precision measuring devices requiring a 0.7820-inch reference diameter.

Installation Notes

Plug pin gages are handled and used by quality technicians and machinists; no installation is required. Store the gage in its protective case when not in use to prevent surface damage and maintain calibration integrity. Clean contact surfaces before each use and avoid dropping or impacting the gage, as this can alter its geometry and invalidate its tolerance class. Periodic recalibration against NIST-traceable standards is recommended per your facility quality management plan.
