Vermont Gage 111311550 Class Zz Plus Plug Gage 0.1155 in

Product Description

The VERMONT GAGE 111311550 is a Class ZZ Plus plug gage used to verify bore and hole diameters to a precision tolerance of 0.0002 inches. Built from tool steel and finished to a 10 microfinish surface, this gage delivers consistent, repeatable measurements in go-inspection applications. At 2.0 inches overall length, it is sized for easy single-hand use. Each unit ships with a Certificate of Accuracy with NIST traceability, making it audit-ready for quality-controlled environments. Machinists, toolroom technicians, and quality control inspectors rely on this type of gage for day-to-day dimensional verification on production and inspection floors.

This plug gage is intended for go-inspection use, confirming that a drilled, reamed, or bored hole meets the minimum acceptable diameter. It is also used to set and verify micrometers, verniers, and other measuring devices. Typical applications include machine shops, tool and die operations, and manufacturing QC departments where ASME B89.1 measurement standards are observed. The 0.1155 inch diameter range suits small-bore verification tasks common in precision component manufacturing.

Key Features

• Class ZZ Plus tolerance of 0.0002 inches for precise go-inspection verification
• Tool steel construction for durability and wear resistance in production environments
• 10 microfinish surface for consistent, low-friction gage entry
• Includes Certificate of Accuracy with NIST traceability for quality documentation
• Meets ASME B89.1 dimensional measurement standards
• Compact 2.0 inch overall length for easy handling and storage

Compatibility

Designed for go-inspection of holes and bores at 0.1155 inches diameter, and for setting and verifying micrometers, verniers, and other precision measuring devices per ASME B89.1 requirements.

Installation Notes

This gage is handled and used by toolroom technicians, machinists, and QC inspectors — no power source or mechanical installation is required. Ensure all equipment being gaged or set is stationary and free of chips, coolant, or debris before use. Handle with clean, dry hands or cotton gloves to prevent corrosion from skin oils. Store in a protective case away from abrasive tools to preserve the microfinish surface and maintain calibration integrity.
