Vermont Gage 112105320 Class Zz Plus Plug Gage 5.32 Mm

Product Description

The VERMONT GAGE 112105320 is a Class ZZ Plus plug gage machined from tool steel for dimensional inspection of bore diameters. It measures 5.32 mm in diameter with a tolerance of 0.00508 mm and features a 10 microfinish surface on the gaging member. Overall length is 2.0000 inches. Each unit ships with a Certificate of Accuracy traceable to NIST, confirming conformance to ASME B89.1. Machinists, quality technicians, and metrologists use this gage to verify that a hole or bore meets its go-limit specification before the workpiece advances to the next stage of production.

This plug gage is suited for go inspection applications in production and inspection environments. It is compatible with go/no-go gage handle systems and is commonly used alongside set micrometers, verniers, and other measuring devices for process control. The 5.32 mm diameter makes it appropriate for small-bore verification in precision machined components. It fits residential shop, job-shop, and industrial quality-control workflows where consistent bore acceptance criteria are required.

Key Features

• Class ZZ Plus tolerance rating per ASME B89.1 for go-limit bore inspection
• 5.32 mm diameter with 0.00508 mm tolerance for precise acceptance gaging
• 10 microfinish surface finish on gaging member minimizes wear and measurement error
• Tool steel construction provides hardness and durability for repeated use
• Includes Certificate of Accuracy with NIST traceability for audit and calibration records
• Overall length of 2.0000 inches compatible with standard gage handle assemblies

Compatibility

Designed for go inspection use with set micrometers, verniers, and other measuring devices as stated by the manufacturer. Intended for use with standard plug gage handle assemblies appropriate for the 5.32 mm diameter class.

Installation Notes

Plug gages are handled and used by quality technicians and machinists; no power tools or electrical shutoff is required. Keep the gaging surface clean and lightly oiled when not in use to prevent corrosion of the tool steel. Do not force the gage into a bore; go gages should enter under their own weight or with light hand pressure only. Store in the original case or a protected gage block tray to preserve the 10 microfinish surface and calibration integrity.
