Vermont Gage 111169900 Class Zz Plus Plug Gage 0.699 in

Product Description

The VERMONT GAGE 111169900 is a Class ZZ Plus plug gage machined to a 0.699-inch nominal diameter with a tolerance of 0.0002 inches. Built from tool steel, it delivers the dimensional accuracy required for go inspection tasks in production and quality-control environments. The 10 microinch surface finish ensures consistent, repeatable contact with bored holes, reamed bores, and other precision features. Each unit ships with a Certificate of Accuracy traceable to NIST, meeting ASME B89.1 standards. Machinists, toolroom technicians, and quality inspectors rely on this gage to verify hole sizes before parts advance to the next stage of manufacturing or assembly.

This plug gage is suited for go inspection of through-holes and blind bores at 0.699 inches nominal diameter. It is also used to calibrate and verify the accuracy of set micrometers, verniers, and other measuring devices where a traceable, hardened reference is required. Typical applications include precision machining shops, tool-and-die operations, and quality labs operating under ISO or ASME-controlled measurement systems. At 2.0 inches overall length, the gage is compact enough for benchtop or floor use in high-throughput inspection routines.

Key Features

• Class ZZ Plus tolerance of 0.0002 inches for tight go-inspection accuracy
• Tool steel construction for hardness and wear resistance in frequent-use environments
• 10 microinch surface finish for consistent, repeatable gage contact
• Meets ASME B89.1 dimensional standards
• Includes Certificate of Accuracy with NIST traceability
• Compact 2.0-inch overall length suits benchtop and floor inspection stations

Compatibility

Designed for go inspection of 0.699-inch nominal diameter bores and as a setting reference for micrometers, verniers, and other precision measuring devices requiring a traceable hardened master.

Installation Notes

Plug gages should be handled by quality technicians or toolroom personnel familiar with ASME B89.1 gage-handling practices. Clean the gage and the bore with a lint-free cloth before use to prevent contamination from affecting measurement results. Store the gage in its protective case when not in use to prevent surface damage. Do not force the gage into a bore; light hand pressure is sufficient for a go check.
