Vermont Gage 112216420 Class Zz Minus Plug Pin Gage 16.42mm

Product Description

The VERMONT GAGE 112216420 is a Class ZZ Minus plug pin gage designed for precise dimensional inspection in machining and manufacturing environments. Measuring 16.42 mm in diameter with a tolerance of 0.00508 mm, this pin gage delivers the accuracy required for NoGo inspection work. The steel construction and 10 micro coating finish support consistent, repeatable measurements across high-use inspection cycles. Each unit ships with a Certificate of Accuracy traceable to NIST standards, making it suitable for quality-controlled environments where documentation is required. Metrology technicians, machinists, and quality control professionals are the primary users of this tool.

This plug pin gage is used in applications requiring precise bore and hole diameter verification, specifically as a NoGo gage in go/no-go inspection routines. It is also suited for setting micrometers, verniers, and other measuring devices that require a known reference diameter. At 16.42 mm, this gage fits into inspection workflows for medium-range bore sizes common in precision machined components. It is appropriate for both shop-floor and metrology lab environments where Class ZZ tolerance levels are specified.

Key Features

• Class ZZ Minus tolerance rating with 0.00508 mm tolerance for precision NoGo inspection

• Steel construction with 10 micro coating finish for durability and surface consistency
• Overall length of 2 inches for comfortable handling and access in standard inspection setups
• Includes Certificate of Accuracy with NIST traceability for documented quality assurance
• Suitable for setting micrometers, verniers, and other calibrated measuring devices

Compatibility

Designed for use in NoGo inspection applications and as a reference standard for setting micrometers, verniers, and other measuring devices requiring a 16.42 mm diameter reference.

Installation Notes

Handle with clean, dry hands or lint-free gloves to prevent surface contamination that can affect measurement accuracy. Store in a protective case away from temperature extremes to maintain dimensional stability. Calibration intervals should follow your facility quality management plan and applicable metrology standards. Do not force the gage into bores that show resistance, as this can damage both the gage and the workpiece.
