Vermont Gage 112302630 Class Zz Plus Plug Gage 2.63mm

Product Description

The VERMONT GAGE 112302630 is a Class ZZ Plus plug gage designed for precision dimensional inspection of small bores and holes. Manufactured from tool steel, this pin-style gage measures 2.63 mm in diameter with a tolerance of 0.00508 mm (0.005 mm), making it suitable for high-accuracy go inspection workflows. The contact surface carries a 10 microfinish rating, ensuring consistent, repeatable gauge contact. At 0.01 pounds, it is a compact, single-pin gage suited for use in quality control environments, tool rooms, and production floor inspection stations. Each unit ships with a Certificate of Accuracy backed by NIST traceability, meeting ASME B89.1 standards.

This plug gage is used in go inspection applications to verify that a drilled, reamed, or bored hole meets the minimum acceptable size before a part advances in production. It is compatible with standard gage handle systems and is commonly used alongside set micrometers, verniers, and other calibrated measuring devices. Typical users include machinists, quality technicians, and metrology lab personnel working in precision manufacturing, aerospace, automotive, and general industrial environments where close-tolerance hole verification is required.

Key Features

• 2.63 mm diameter with 0.00508 mm tolerance for tight go inspection control
• 10 microfinish surface for consistent, low-friction gauge contact
• Tool steel construction for hardness and long service life
• Meets ASME B89.1 dimensional gage standards
• Includes Certificate of Accuracy with NIST traceability
• Lightweight at 0.01 pounds for fatigue-free repetitive inspection use

Compatibility

Designed for use in go inspection applications with standard plug gage handles and compatible with set micrometers, verniers, and other calibrated measuring devices as noted in the product specification.

Installation Notes

Plug gages should be handled with clean, dry hands or lint-free gloves to prevent surface contamination and corrosion on the tool steel pin. Before use, verify the gage has thermally stabilized to ambient temperature, as thermal expansion can affect measurement accuracy at this tolerance level. Store in a protective case when not in use to prevent nicking or scratching the precision ground surface. Calibration intervals should follow your facility quality management system and applicable metrology standards.
