Vermont Gage 111168300 Class Zz Plus Plug Gage 0.683 in

Product Description

The VERMONT GAGE 111168300 is a Class ZZ Plus plug gage used to verify bore and hole diameters in precision machining and inspection environments. It measures 0.683 inches in diameter with a tolerance of 0.0002 inches and features a 10 microfinish surface on the gage member. The overall length is 2.0 inches. Made from tool steel, this plug gage is built to withstand repeated use in shop-floor and quality-lab settings. Each unit ships with a Certificate of Accuracy with NIST Traceability, meeting the documentation requirements of most quality management systems. Dimensional compliance is per ASME B89.1.

This plug gage is suited for go inspection applications where confirming that a hole or bore accepts a minimum acceptable diameter is required. It is also appropriate for setting and verifying micrometers, verniers, and other measuring devices. Typical users include machinists, quality technicians, and metrology professionals working in production, tool-and-die, or inspection environments where tight dimensional tolerances must be confirmed before parts advance through the manufacturing process.

Key Features

• 0.683 inches measurement diameter for precise bore inspection
• Class ZZ Plus tolerance of 0.0002 inches for reliable go-inspection accuracy
• 10 microfinish surface for consistent gage-member contact and reduced wear
• Tool steel construction for durability in production and inspection use
• Includes Certificate of Accuracy with NIST Traceability
• Conforms to ASME B89.1 dimensional standards

Compatibility

Designed for go inspection use with micrometers, verniers, and other measuring devices requiring a 0.683-inch reference standard. Suitable for any application governed by ASME B89.1 gage standards.

Installation Notes

Plug gages are handled and used by quality technicians and machinists — no power source or utility shutoff is required. Store and handle with clean cotton gloves or a lint-free cloth to prevent corrosion from skin oils. Do not force the gage into a hole; apply only light, controlled hand pressure to avoid damage to the gage or the workpiece. Calibration intervals should follow your facility quality plan and applicable metrology standards.
