Vermont Gage 112200900 Class Zz Minus Plug Pin Gage 0.90 Mm

Product Description

The VERMONT GAGE 112200900 is a Class ZZ Minus plug pin gage designed for precision dimensional inspection at a 0.90 mm diameter. It carries a tolerance of 0.00508 mm and is manufactured from steel with a 10 microfinish surface coating. This pin gage is used to verify that a hole or bore does not exceed its maximum allowable size, functioning as a NoGo gage in go/no-go inspection workflows. Each unit ships with a Certificate of Accuracy with NIST Traceability, confirming calibration to a recognized national standard. Metrology technicians, machinists, and quality control inspectors are the primary users of this tool.

This pin gage is suited for inspection of small-diameter bores and holes in manufacturing, machining, and quality assurance environments. Typical applications include NoGo inspection of precision-machined parts and use alongside set micrometers, verniers, and other dimensional measuring devices. Its compact 2-inch overall length makes it practical for bench or floor inspection stations. The included NIST-traceable certificate supports use in environments where documented calibration records are required.

Key Features

• Class ZZ Minus tolerance class — 0.00508 mm tolerance for NoGo inspection use
• Steel construction with 10 microfinish surface for consistent, repeatable contact
• Certificate of Accuracy with NIST Traceability included with each unit
• Compatible with set micrometers, verniers, and other precision measuring devices
• Compact 2-inch overall length for easy handling at inspection stations

Compatibility

Designed for use in NoGo inspection applications alongside set micrometers, verniers, and other precision measuring devices requiring a 0.90 mm diameter reference standard.

Installation Notes

Pin gages are handled by metrology and quality control personnel and require no mechanical installation. Keep gage surfaces clean and free of debris before use to avoid measurement error. Store in a protective case away from moisture and temperature extremes to maintain calibration integrity. Handle with care to prevent surface damage that could affect dimensional accuracy.
