Vermont Gage 112405470 Class Zz Minus Plug Pin Gage 5.47mm

Product Description

The VERMONT GAGE 112405470 is a Class ZZ minus plug pin gage machined from steel and used for dimensional inspection of small bores and holes. It measures 5.47 mm in diameter with a tolerance of 0.00508 mm, making it suitable for NoGo inspection applications where precise rejection of out-of-tolerance parts is required. The overall length is 2 inches. Each gage ships with a Certificate of Accuracy that carries NIST traceability, supporting documented quality control programs. Metrology technicians, toolroom machinists, and quality inspectors use this type of gage in production and incoming inspection environments.

This pin gage is intended for NoGo inspection work, where it confirms that a bore or hole does not exceed the maximum allowable size. It is also suited for setting micrometers, verniers, and other measuring devices that require a traceable reference. Typical applications include incoming part inspection, in-process quality checks, and tooling verification in manufacturing and machine shop settings. The 10 microfinish surface coating supports accurate, repeatable contact with the workpiece.

Key Features

• Class ZZ minus tolerance classification for NoGo inspection use
• 5.47 mm diameter with 0.00508 mm tolerance for tight dimensional control
• Steel construction with 10 microfinish surface for consistent, repeatable measurement contact
• Includes Certificate of Accuracy with NIST traceability for documented quality programs
• 2 inch overall length suits standard pin gage handles and collet-style holders

Compatibility

Suitable for use in NoGo bore inspection, setting of micrometers, verniers, and other measuring devices requiring a traceable 5.47 mm reference standard.

Installation Notes

Pin gages are handled and used by metrology technicians and quality inspectors. Keep the gage clean and lightly oiled when not in use to prevent corrosion on the steel surface. Always insert and withdraw the pin gage along the bore axis without side-loading to preserve the surface finish and avoid false readings. Store in the original case or a padded holder to protect the finished diameter from nicks and wear.
