Vermont Gage 112422290 Class Zz Minus Plug Pin Gage 22.29mm

Product Description

The VERMONT GAGE 112422290 is a Class ZZ Minus plug pin gage machined from steel and used to verify bore diameters with a NoGo inspection pass. It measures a nominal diameter of 22.29 mm with a tolerance of 0.00508 mm, delivering the tight dimensional control required for precision inspection work. The gage carries a Certificate of Accuracy with NIST traceability, making it suitable for quality-assurance environments where documented calibration records are required. At 2 inches in overall length and 0.35 pounds, it handles easily in production or tool-room inspection routines. Machinists, quality technicians, and metrologists install and use this type of gage as part of dimensional verification programs.

This plug pin gage is intended for NoGo inspection applications where a bore or hole must be confirmed to be within a specified maximum limit. It is also suited for setting and verifying micrometers, verniers, and other measuring devices requiring a known reference diameter. The Class ZZ Minus designation indicates the tolerance is applied in the minus direction from nominal, which is standard practice for NoGo members in a Go/NoGo gage pair used in light manufacturing, tool-and-die, and precision machining environments.

Key Features

• Class ZZ Minus tolerance classification for NoGo bore inspection
• 22.29 mm nominal measurement diameter with 0.00508 mm tolerance
• Steel construction for durability and dimensional stability
• 10 micro coating and finish for surface consistency
• Includes Certificate of Accuracy with NIST traceability
• 2 inches overall length for comfortable single-hand use

Compatibility

Designed for use in NoGo inspection applications and as a reference standard for setting micrometers, verniers, and other precision measuring devices requiring a 22.29 mm reference diameter.

Installation Notes

Plug pin gages are handled and used by quality technicians and machinists and do not require power-down procedures. Keep the gage clean and lightly oiled when not in use to prevent corrosion and dimensional change. Never force the gage into a bore; if resistance is met, inspect the bore separately. Store in a protective case away from temperature extremes to maintain calibration integrity.
