Vermont Gage 111308350 Class Zz Plus Plug Gage 0.0835 in

Product Description

The VERMONT GAGE 111308350 is a Class ZZ Plus plug gage designed for precise hole diameter inspection in industrial and manufacturing environments. Built from tool steel with a 10 microfinish surface, this gage measures a nominal diameter of 0.0835 inches with a tolerance of 0.0002 inches. It is used to verify that drilled, reamed, or otherwise machined bores conform to specified dimensional limits. Machinists, quality control technicians, and toolroom personnel use plug gages like this one as part of go inspection routines to confirm hole acceptability without relying on graduated measuring instruments. Each unit ships with a Certificate of Accuracy that includes NIST traceability.

This plug gage is suited for go inspection applications where fast, reliable attribute gauging is required on production floors, in toolrooms, or in quality labs. It is also used as a setting standard or reference device for setting micrometers, verniers, and other measuring instruments. The 0.0835-inch diameter targets small-bore applications common in precision machining, instrument manufacturing, and tight-tolerance assembly work. The 2.0-inch overall length provides adequate handling clearance for use in shallow and moderate-depth bores.

Key Features

• Class ZZ Plus tolerance grade with 0.0002-inch dimensional tolerance for reliable go inspection
• 10 microfinish surface for smooth, consistent gage entry and reduced bore wear
• Tool steel construction for hardness and long service life in production use
• Meets ASME B89.1 standards for dimensional gaging accuracy
• Includes Certificate of Accuracy with NIST traceability for calibration documentation
• Usable as a setting reference for micrometers, verniers, and other measuring devices

Compatibility

Designed for go inspection of holes and bores machined to a 0.0835-inch nominal diameter. Also suitable for setting and verifying micrometers, verniers, and other precision measuring devices requiring a certified reference standard at this diameter.

Installation Notes

Plug gages are handled and used by machinists and quality technicians — no power source or utility shutoff is required. Store the gage in its protective case when not in use to prevent corrosion and surface damage. Apply a light film of instrument oil during storage to maintain the tool steel surface. Handle with clean cotton gloves or lint-free cloth to prevent thermal expansion errors from hand heat and to protect the microfinish surface.
