Vermont Gage 112206540 Class Zz Minus Plug Pin Gage 6.54mm

Product Description

The VERMONT GAGE 112206540 is a Class ZZ Minus plug pin gage designed for precision dimensional inspection. It measures a nominal diameter of 6.54 mm with a tolerance of 0.00508 mm, making it suitable for NoGo inspection applications where close-tolerance verification is required. The gage is machined from steel and features a 10 microfinish surface coating for consistent, repeatable contact. Overall length is 2 inches. Each unit ships with a Certificate of Accuracy traceable to NIST standards, supporting quality documentation requirements in manufacturing and metrology environments. Dimensional inspection professionals, quality technicians, and tool room machinists are the primary users.

This plug pin gage is used in NoGo inspection routines to verify that a bore or hole does not exceed its maximum allowable size. It is compatible with standard gage block setups and is appropriate for calibrating or checking micrometers, verniers, and other measuring devices. Typical applications include incoming inspection, in-process quality control, and final verification on machined components in precision manufacturing environments. The Class ZZ minus designation indicates this is a working-grade gage ground to minus tolerance, meaning the gage itself falls below the nominal size within the stated tolerance band.

Key Features

• Class ZZ Minus tolerance designation for NoGo inspection use
• 6.54 mm nominal diameter with 0.00508 mm tolerance
• Steel construction with 10 microfinish surface coating for repeatable contact
• 2 inch overall length for standard gage handle compatibility
• Includes Certificate of Accuracy with NIST traceability for documentation compliance
• Suitable for setting micrometers, verniers, and other precision measuring instruments

Compatibility

Designed for use as a NoGo plug gage in standard pin gage handle systems and compatible with micrometers, verniers, and other measuring devices requiring a 6.54 mm reference standard.

Installation Notes

Plug pin gages are handled and used by quality technicians and tool room personnel - no mechanical installation is required. Store the gage in its protective case when not in use to prevent surface damage or corrosion. Clean contact surfaces with a lint-free cloth before each use to ensure accurate measurement. Avoid dropping or forcing the gage into a bore, as impact or side loading can alter the calibrated surface.
