Vermont Gage 112209820 Class Zz Minus Plug Pin Gage 9.82mm

Product Description

The VERMONT GAGE 112209820 is a Class ZZ Minus plug pin gage designed for precision dimensional inspection. It measures 9.82 mm in diameter and carries a tolerance of 0.00508 mm, making it suited for NoGo inspection applications where tight dimensional verification is required. The gage is machined from steel with a 10 microfinish surface coating for consistent contact and accurate readings. A Certificate of Accuracy with NIST traceability is included, supporting calibration records and quality-system documentation. Overall length is 2 inches. Metrology technicians, quality control inspectors, and machinists use this type of gage in production and inspection environments.

This plug pin gage is intended for NoGo inspection work and is also used with set micrometers, verniers, and other precision measuring devices. It is appropriate for both job-shop and production-floor inspection of machined bores, holes, and features requiring close-tolerance verification. The 9.82 mm diameter and Class ZZ Minus classification position it for use where standard gage tolerances must be maintained per industry practice. The included NIST-traceable Certificate of Accuracy supports ISO 9001, AS9100, and similar quality programs.

Key Features

• Class ZZ Minus tolerance classification: 0.00508 mm tolerance for precise NoGo inspection
• 9.82 mm measurement diameter in a 2-inch overall length form factor
• Steel construction with 10 microfinish surface coating for repeatable contact
• Includes Certificate of Accuracy with NIST traceability for quality-system compliance
• Compatible with set micrometers, verniers, and other calibrated measuring instruments

Compatibility

Designed for use in NoGo inspection applications and as a reference standard with set micrometers, verniers, and other precision measuring devices requiring a 9.82 mm diameter reference.

Installation Notes

Plug pin gages are handled and used by metrology technicians and quality control personnel. Keep the gage surface clean and lightly oiled when not in use to prevent corrosion on the steel body. Do not drop or strike the gage against hard surfaces, as impact can alter the precision-ground diameter. Store in the supplied case or a protective holder to maintain the 10 microfinish surface condition.
