Vermont Gage 111308150 Class Zz Plus Plug Gage 0.0815 in

Product Description

The VERMONT GAGE 111308150 is a Class ZZ Plus plug gage designed for precision dimensional inspection of holes and bores. Manufactured from tool steel with a 10 microfinish surface, this gage measures a nominal diameter of 0.0815 inches with a tolerance of 0.0002 inches. It is used by quality control technicians, machinists, and metrologists to verify whether a hole falls within acceptable dimensional limits. Each unit ships with a Certificate of Accuracy backed by NIST traceability, confirming conformance to ASME B89.1 standards. Overall length is 2.0000 inches.

This plug gage is suited for go inspection applications in manufacturing and machine shop environments. It is commonly used alongside set micrometers, verniers, and other precision measuring devices to verify hole diameters on machined components in both production and inspection settings. The 0.0815-inch diameter makes it appropriate for small-bore work where tight dimensional control is required. Residential and light industrial fabrication shops as well as high-precision aerospace and tooling operations rely on Class ZZ Plus gages for reliable pass-fail verification.

Key Features

• Class ZZ Plus tolerance class with 0.0002-inch tolerance for precise go inspection
• 10 microfinish surface for consistent, low-friction contact with the bore
• Tool steel construction for hardness and wear resistance
• NIST-traceable Certificate of Accuracy included with each unit
• Conforms to ASME B89.1 dimensional gage standards
• Compact 2.0000-inch overall length suits benchtop and in-line inspection use

Compatibility

Designed as an OEM-style precision inspection gage for go-inspection workflows compatible with set micrometers, verniers, and other calibrated measuring devices as stated by the manufacturer.

Installation Notes

Plug gages are handled and used by quality technicians and machinists; no power tools or utilities need to be shut off before use. Keep the gage clean and lightly oiled when not in use to prevent corrosion on the tool steel surface. Do not force the gage into a bore; apply only light, consistent hand pressure to avoid wear or damage to the gage or workpiece. Store in the provided case or a clean, dry environment to preserve calibration and surface finish.
