Vermont Gage 911116000 Class Zz Plus Plug Gage 0.16 in

Product Description

The VERMONT GAGE 911116000 is a Class ZZ Plus plug gage designed to perform go inspection on machined bores and internal features. Manufactured from tool steel with a black oxide finish, this single-ended plug gage measures 0.16 inches in diameter and holds a tolerance of 0.0002 inches. It ships with a Certificate of Accuracy with NIST Traceability, confirming dimensional compliance to ASME B89.1 standards. Machinists, tool-room technicians, and quality control inspectors use this type of gage to verify that drilled, reamed, or bored holes fall within acceptable size limits before parts advance to the next stage of production.

This plug gage suits go inspection applications where confirming minimum acceptable bore size is critical. It is also used to set and verify micrometers, verniers, and other measuring devices in shop or lab environments. The 0.16-inch diameter range targets small-bore work common in precision machining, instrument manufacturing, and tight-tolerance fabrication. Its compact overall length of 2.0 inches keeps it manageable in confined inspection setups. Licensed machinists and quality technicians in both job-shop and production environments will find it appropriate for routine attribute gaging tasks.

Key Features

• Class ZZ Plus tolerance grade with 0.0002-inch tolerance for precise go inspection
• Tool steel construction for hardness and dimensional stability over repeated use
• Black oxide finish resists corrosion and reduces light reflection during inspection
• Includes Certificate of Accuracy with NIST Traceability
• Conforms to ASME B89.1 dimensional standards
• Compact 2.0-inch overall length suits small-bore and tight-clearance inspection

Compatibility

Designed as a go-inspection plug gage for use with bores measuring 0.16 inches in diameter. Also suitable for setting and verifying micrometers, verniers, and other precision measuring devices in accordance with ASME B89.1.

Installation Notes

Plug gages should be handled with clean, dry hands or lint-free gloves to prevent contamination that could affect readings. Before use, clean the bore and gage contact surfaces with an appropriate solvent and allow them to reach the same ambient temperature to avoid thermal expansion errors. Do not force the gage through the bore; controlled, steady hand pressure is the correct technique. Store the gage in a protective case away from other tools to prevent nicking the precision-ground surface.
