Vermont Gage 112108280 Class Zz Plus Plug Gage 8.28 Mm

Product Description

The VERMONT GAGE 112108280 is a Class ZZ Plus plug gage machined from tool steel for dimensional inspection of bored holes and machined features. Sized at 8.28 mm in diameter with a tolerance of 0.00508 mm, this gage delivers the precise go-inspection verification required in production and quality-control environments. The 10 microfinish surface coating reduces wear and maintains dimensional accuracy over repeated use cycles. Each unit ships with a Certificate of Accuracy traceable to NIST standards, satisfying documentation requirements for ISO and AS9100 quality systems. Metrology technicians, machinists, and quality engineers rely on this class of gage for fast, reliable attribute inspection on the shop floor or in the inspection lab.

This plug gage is suited for go-inspection of holes measuring 8.28 mm in diameter across a range of machined components in manufacturing, toolroom, and incoming inspection settings. It is also used to set and verify micrometers, verniers, and other measuring devices where a known reference size is required. The overall length of 2.0000 inches makes it compatible with standard gage handle assemblies used in typical bench inspection setups. Professionals performing first-article inspection, in-process checks, or final acceptance testing will find this gage a direct fit for those workflows.

Key Features

• Class ZZ Plus tolerance of 0.00508 mm for high-accuracy go-inspection applications
• Tool steel construction for durability and resistance to wear in production environments
• 10 microfinish surface coating maintains dimensional integrity over extended service life
• Includes Certificate of Accuracy with NIST traceability for quality system documentation
• Conforms to ASME B89.1 standards for plain plug gages
• Overall length of 2.0000 inches compatible with standard gage handle assemblies

Compatibility

Designed for use as a go plug gage for 8.28 mm diameter features and as a reference standard for setting micrometers, verniers, and other calibrated measuring devices per ASME B89.1.

Installation Notes

Plug gages are handled and used by metrology technicians and quality control personnel - no power tools or utilities need to be shut down prior to use. Store the gage in its protective case when not in use and avoid dropping or impact that could alter the calibrated diameter. Clean the gage and the workpiece bore with a lint-free cloth before inspection to prevent debris from causing false readings. Re-verify calibration status against the Certificate of Accuracy at intervals consistent with your facility quality plan.
