Vermont Gage 111104000 Class Zz Plus Plug Gage 0.04 in

Product Description

The VERMONT GAGE 111104000 is a Class ZZ Plus plug gage manufactured from tool steel for precise dimensional inspection of small bores and holes. It measures a nominal diameter of 0.04 inches with a tolerance of 0.0002 inches, and the gaging surface carries a 10 microfinish for consistent, repeatable contact. At 2.0 inches overall length, the gage is sized for easy one-hand handling during bench or in-process checks. Each unit ships with a Certificate of Accuracy traceable to NIST, satisfying documentation requirements for ISO-registered shops and quality audits. Machinists, tool room technicians, and quality control inspectors install and use this gage in production and inspection environments.

This plug gage is designed for go inspection of drilled, reamed, or bored holes at the 0.04-inch nominal size. It is also suited for setting and verifying micrometers, verniers, and other precision measuring devices to a known reference. Typical applications include incoming inspection, first-article verification, and process control checks in machine shops, toolrooms, and manufacturing facilities. The Class ZZ Plus designation indicates an above-standard tolerance grade appropriate for master or reference use where higher accuracy than standard working gages is required. Conforms to ASME B89.1 dimensional standards.

Key Features

• 10 microfinish gaging surface reduces wear and ensures consistent contact
• Tool steel construction provides hardness and durability for repeated use
• 2.0-inch overall length suits bench and in-process inspection tasks
• Certificate of Accuracy with NIST traceability included for quality documentation
• Conforms to ASME B89.1 standards

Compatibility

Designed for go inspection of bores and holes at 0.04-inch nominal diameter, and for use as a reference standard when setting micrometers, verniers, and other precision measuring devices.

Installation Notes

Plug gages are handled and stored by quality technicians and tool room personnel following standard metrology practices. Keep the gaging surface clean and lightly oiled when not in use to prevent corrosion of the tool steel. Do not force the gage into an undersized bore, as this can damage the gaging surface and alter calibration. Store in the original case or protective holder away from other tooling to preserve the 10 microfinish surface finish.
