Vermont Gage 112316050 Class Zz Plus Plug Gage 16.05mm

Product Description

The VERMONT GAGE 112316050 is a Class ZZ Plus plug gage designed for go inspection of bored, reamed, and machined holes with a nominal diameter of 16.05 mm. Built from tool steel, it delivers a tolerance of 0.00508 mm and a 10 microfinish surface, meeting the tight accuracy demands required for production and quality-control environments. Each gage ships with a Certificate of Accuracy traceable to NIST, supporting documentation requirements in ISO-registered and aerospace shops. Machinists, quality technicians, and toolroom personnel use this gage to verify that a hole falls within its lower acceptance limit during go/no-go inspection routines.

This plug gage is suited for use in dimensional inspection stations where hole diameter must be confirmed before a part advances to the next operation. Typical applications include verifying CNC-machined bores, reamed holes, and press-fit features in both job-shop and high-volume production settings. It is also appropriate for calibrating and setting micrometers, verniers, and other comparative measuring devices requiring a traceable reference standard. The overall length of 2.0000 inches makes it compatible with standard gage handle systems used across the trade.

Key Features

• Class ZZ Plus tolerance of 0.00508 mm for high-accuracy go inspection
• 10 microfinish surface for consistent, repeatable gage contact
• Tool steel construction for durability in production environments
• Includes Certificate of Accuracy with NIST traceability
• Conforms to ASME B89.1 dimensional gage standards
• Overall length of 2.0000 inches fits standard plug gage handles

Compatibility

Designed as an OEM-style replacement and standard go plug gage for use with conventional gage handle systems; suitable for go inspection, setting micrometers, verniers, and other measuring devices as noted in the product specifications.

Installation Notes

Plug gages should be handled by quality technicians or toolroom personnel familiar with ASME B89.1 inspection practices. Clean the gage and the workpiece bore thoroughly before use to prevent false readings caused by chips or coolant residue. Never force the gage into a hole; go gages should enter under the weight of the gage or light hand pressure only. Store the gage in its protective case when not in use to preserve the ground surface and calibration integrity.
