Vermont Gage 111112500 Class Zz Plus Plug Gage 0.125 in

Product Description

The VERMONT GAGE 111112500 is a Class ZZ Plus plug gage designed for precision go inspection of hole diameters at 0.125 inches. Manufactured from tool steel, it delivers a tolerance of 0.0002 inches and a 10 microfinish surface, meeting the tight requirements of dimensional inspection work. At 2.0 inches overall length, it is sized for straightforward use with hand-held inspection setups. Each unit ships with a Certificate of Accuracy with NIST Traceability, confirming it meets ASME B89.1 standards. Machinists, quality control technicians, and tool room personnel use this gage to verify bore and hole dimensions quickly and reliably.

This plug gage is suited for go inspection applications in manufacturing and quality assurance environments. It is used alongside set micrometers, verniers, and other precision measuring devices to verify that machined holes fall within acceptable dimensional limits. The 0.125 inch diameter makes it applicable to small-bore inspection tasks common in precision machining, aerospace component verification, and general metalworking quality control. Its tool steel construction holds up under repeated use in shop floor conditions.

Key Features

• Class ZZ Plus tolerance of 0.0002 inches for high-accuracy go inspection
• 10 microfinish surface for consistent, repeatable gage contact
• Tool steel construction for durability under repeated shop use
• ASME B89.1 compliant dimensional standards
• Includes Certificate of Accuracy with NIST Traceability
• Compatible with set micrometers, verniers, and other precision measuring devices

Compatibility

Designed for use in go inspection applications with set micrometers, verniers, and other precision measuring devices where 0.125 inch diameter hole verification is required.

Installation Notes

Plug gages are handled and used by quality control technicians and machinists in inspection environments. 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; excessive insertion force can damage both the gage and the workpiece. Store in a protective case away from other tooling to preserve the microfinish and dimensional accuracy.
