Vermont Gage 111162400 Class Zz Plus Plug Gage 0.624 in

Product Description

The VERMONT GAGE 111162400 is a Class ZZ Plus plug gage machined from tool steel for dimensional inspection of bores and holes at 0.624 inches diameter. It carries a tolerance of 0.0002 inches and a 10 microfinish surface condition, giving inspection technicians and machinists a reliable go-inspection reference. Each unit ships with a Certificate of Accuracy traceable to NIST, confirming conformance to ASME B89.1 standards. The overall length is 2.0 inches. This gage is suited for quality control personnel, toolroom machinists, and calibration technicians who need a traceable, single-diameter go reference in production or lab environments.

The 111162400 is used in go inspection applications to verify that a machined bore or hole falls within the minimum acceptable size limit. It is also used to set and verify micrometers, verniers, and other measuring devices requiring a known reference diameter. Typical deployment is in toolrooms, machine shops, inspection labs, and manufacturing quality control stations where ASME B89.1 compliance is required. The 0.624-inch diameter addresses a commonly encountered bore size in precision machined components across general manufacturing and mechanical assembly operations.

Key Features

• Class ZZ Plus tolerance of 0.0002 inches for precision go inspection
• 10 microfinish surface for accurate, repeatable contact measurement
• Tool steel construction for durability and dimensional stability
• 2.0-inch overall length for comfortable handling and gauge access
• Certificate of Accuracy included with NIST traceability
• Conforms to ASME B89.1 dimensional gage standards

Compatibility

Designed for go inspection use and as a setting reference for micrometers, verniers, and other measuring devices requiring a 0.624-inch diameter reference standard per ASME B89.1.

Installation Notes

Plug gages of this type are handled and used by quality control technicians and toolroom machinists without requiring power tools or disassembly of live equipment. Keep the gage clean and lightly oiled when stored to prevent corrosion of the tool steel. Do not force the gage into a bore; apply light, consistent hand pressure only. Store in the provided case or a protective sleeve to preserve the 10 microfinish surface and dimensional integrity.
