Vermont Gage 112317090 Class Zz Plus Plug Gage 17.09mm

Product Description

The VERMONT GAGE 112317090 is a Class ZZ Plus plug gage designed for go inspection of bored holes, machined features, and precision-fit components requiring consistent diameter verification. The gage measures 17.09 mm in diameter and holds a tolerance of 0.00508 mm, making it suitable for quality-control workflows that demand tight dimensional accountability. The 10 microinch surface finish on the plug face supports accurate, repeatable contact with the workpiece. Each unit ships with a Certificate of Accuracy that carries NIST traceability, meeting documentation requirements for ISO-compliant inspection environments. Machinists, tool-and-die technicians, and quality inspectors install and use this gage in production and inspection settings.

This plug gage is appropriate for go inspection tasks on precision-machined bores in both shop-floor and metrology-lab environments. It works alongside set micrometers, verniers, and other calibrated measuring devices to confirm that finished features fall within allowable dimensional limits. The 2.0 inch overall length provides adequate handle clearance for use with standard gage handles. Applications span general manufacturing, aerospace component inspection, hydraulic and pneumatic fitting verification, and any production process governed by ASME B89.1 dimensional standards.

Key Features

• 17.09 mm nominal diameter for precise bore inspection
• Class ZZ Plus tolerance of 0.00508 mm for tight dimensional control
• 10 microinch surface finish for consistent, repeatable gage contact
• Includes Certificate of Accuracy with NIST traceability
• Manufactured from tool steel for durability in repeated-use inspection cycles
• Conforms to ASME B89.1 standards

Compatibility

Designed as an OEM-style go plug gage for use with standard gage handle systems accepting 17.09 mm diameter plug members. Compatible with set micrometers, verniers, and other measuring devices as noted in the product application data.

Installation Notes

Plug gages are typically handled and applied by quality inspectors, machinists, or metrologists in controlled inspection environments. Before use, clean the gage and the bore being checked to remove chips, oil, and debris that could affect contact and reading accuracy. Never force the plug gage into an undersized bore, as this can damage the gage face and compromise its calibration. Store the gage in its case away from other tooling to protect the finished surface and preserve NIST-traceable accuracy.
