Vermont Gage 112305510 Class Zz Plus Plug Gage 5.51 Mm

Product Description

The VERMONT GAGE 112305510 is a Class ZZ Plus plug gage used to verify bore and hole diameters in precision inspection work. It measures 5.51 mm in diameter with a tolerance of 0.00508 mm, making it suitable for Go inspection applications where tight dimensional control is required. Constructed from tool steel with a 10 microfinish surface, it delivers the durability and surface quality needed for repeatable, accurate measurements. Each unit ships with a Certificate of Accuracy traceable to NIST, confirming it meets ASME B89.1 standards. Metrology technicians, machinists, and quality control inspectors use this gage in production and inspection environments.

This plug gage is designed for Go inspection use and is compatible with setup and verification tasks involving set micrometers, verniers, and other measuring devices. It is suited for both shop-floor and lab environments where precise hole diameter verification is part of a standard quality control workflow. Its compact size and tool steel construction make it practical for everyday use on machined components requiring tight tolerance verification.

Installation Notes

Plug gages are handled and used by metrology technicians and quality control professionals. Always ensure the gage and the workpiece bore are clean and free of debris before use to avoid false readings or surface damage. Store the gage in its protective case when not in use to preserve the microfinish and dimensional accuracy. Do not force the gage into a bore; apply only light, controlled hand pressure consistent with Go gage inspection practice.
