Vermont Gage 111249700 Class Zz Minus Plug Pin Gage 0.4970 in

Product Description

The VERMONT GAGE 111249700 is a Class ZZ Minus plug pin gage machined from steel for dimensional inspection work in tool rooms, production floors, and quality-control environments. The gage measures 0.4970 inches in diameter with a tolerance of 0.0002 inches, meeting Class ZZ minus specifications for NoGo inspection applications. Overall length is 2 inches, giving technicians a secure grip during use. Each unit ships with a Certificate of Accuracy traceable to NIST, making it suitable for processes that require documented measurement traceability. Machinists, quality technicians, and metrology professionals are the primary users of this gage.

This plug pin gage is intended for NoGo go/no-go inspection routines where a hole or bore must not exceed a specified diameter. It is also used to set micrometers, verniers, and other measuring devices to a known diameter reference. Typical applications include incoming inspection, in-process QC checks, and calibration setups in machine shops, manufacturing facilities, and maintenance departments. The 0.4970-inch diameter makes it appropriate for checking bores and holes in that range across a wide variety of machined components and assemblies.

Key Features

• Class ZZ Minus tolerance of 0.0002 inches for NoGo inspection accuracy
• Steel construction for durability and dimensional stability under shop conditions
• 10 microfinish surface coating for consistent, repeatable contact measurement
• Includes Certificate of Accuracy with NIST traceability for documented QC processes
• Compact 2-inch overall length for easy handling in tight inspection setups

Compatibility

Designed for use in NoGo inspection applications and as a reference standard for setting micrometers, verniers, and other measuring devices requiring a 0.4970-inch diameter reference.

Installation Notes

This gage is a precision measuring tool, not an installed component. Handle with clean, dry hands or lint-free gloves to prevent corrosion and contamination of the finished surface. Store in its protective case when not in use to maintain dimensional integrity. Do not force the gage into a bore — any resistance indicates the feature is at or below the NoGo limit, which is the intended inspection result.
