Vermont Gage 112109340 Class Zz Plus Plug Gage 9.34mm

Product Description

The VERMONT GAGE 112109340 is a Class ZZ Plus plug gage machined from tool steel for dimensional inspection of hole diameters. It is designed for go-inspection applications and delivers a 10 microfinish surface quality on the gage pin. The nominal diameter is 9.34 mm with a tolerance of 0.005 mm (0.00508 mm actual). Overall length is 2.0000 inches. Each unit ships with a Certificate of Accuracy traceable to NIST, making it suitable for documented quality-control workflows. Machinists, toolroom technicians, and quality inspectors use this gage to verify hole conformance on production and inspection floors.

This plug gage is used in go-inspection procedures to confirm that a drilled, reamed, or bored hole meets its minimum size requirement. It is appropriate for use alongside set micrometers, verniers, and other precision measuring devices as noted in the application specification. Typical environments include machine shops, manufacturing cells, and metrology labs where ASME B89.1 inspection standards are observed. The gage is suited for both production floor spot checks and formal inspection station use.

Key Features

• Class ZZ Plus tolerance grade per ASME B89.1
• 9.34 mm nominal diameter with 0.005 mm tolerance
• 10 microfinish surface on the gage pin for accurate, low-wear contact
• Tool steel construction for durability and dimensional stability
• Includes Certificate of Accuracy with NIST traceability for audit-ready documentation
• Overall length of 2.0000 inches fits standard gage handle configurations

Compatibility

Designed for go-inspection use with set micrometers, verniers, and other precision measuring devices per the manufacturer application specification. Conforms to ASME B89.1 standards for plug gage dimensional requirements.

Installation Notes

Plug gages are handled and used by quality technicians and toolroom personnel - no power source or utility shutoff is required. Clean the gage pin and the bore being inspected before use to prevent false readings caused by debris or coolant residue. Do not force the gage into an undersized hole, as this can damage the gage pin surface finish and compromise calibration. Store in the provided case or protective sleeve when not in use to maintain the 10 microfinish surface integrity.
