Vermont Gage 111312350 Class Zz Plus Plug Gage 0.1235 in

Product Description

The VERMONT GAGE 111312350 is a Class ZZ Plus plug gage machined from tool steel for dimensional inspection of holes and bores at 0.1235 inches diameter. It carries a tolerance of 0.0002 inches and a 10 microfinish surface finish, delivering the precision required for Go inspection work on the shop floor or in a metrology lab. Each unit ships with a Certificate of Accuracy traceable to NIST, confirming conformance to ASME B89.1 standards. Licensed machinists, tool and die makers, and quality control technicians use this gage to verify bore dimensions against print tolerances before parts move to the next stage of production.

This plug gage is suited for Go inspection applications in both production and inspection environments. It is compatible with use alongside set micrometers, verniers, and other calibrated measuring devices where a physical reference standard is needed. The 0.1235 inches measurement diameter makes it a common fit for small-bore verification in precision machined components across general manufacturing, aerospace, and tooling operations. Overall length of 2.0 inches provides adequate handling clearance for bench or inline inspection setups.

Key Features

• Class ZZ Plus tolerance grade — 0.0002 inches tolerance for tight dimensional control
• 10 microfinish surface finish minimizes wear on the gage and the workpiece bore
• Tool steel construction for hardness and long service life under repeated use
• Includes Certificate of Accuracy with NIST traceability
• Conforms to ASME B89.1 dimensional gage standards
• Overall length of 2.0 inches for comfortable single-hand operation

Compatibility

Designed for Go inspection use with set micrometers, verniers, and other precision measuring devices requiring a traceable plug gage reference at 0.1235 inches diameter.

Installation Notes

Plug gages are handled and used by quality control technicians and machinists — no permanent installation is required. Store the gage in its protective case when not in use to prevent surface damage and corrosion. Clean the gage and the bore with a lint-free cloth before inspection to remove chips, coolant, or debris that could affect measurement accuracy. Do not force the gage into a bore; excessive force will damage the gage and may invalidate its calibration status.
