Vermont Gage 111327450 Class Zz Plus Plug Gage 0.2745in

Product Description

The VERMONT GAGE 111327450 is a Class ZZ Plus plug gage used to verify the diameter of holes and bores to a high degree of precision. Designed for Go inspection applications, this gage checks that a hole falls within the acceptable tolerance range. It measures 0.2745 inches in diameter with a tolerance of 0.0002 inches and features a 10 microfinish surface. Machined from tool steel for durability and dimensional stability, it is an essential hand tool for quality control technicians, machinists, and metrology professionals working in manufacturing and inspection environments.

This plug gage is suited for use with setting micrometers, vernier calipers, and other precision measuring devices in both production floor and inspection lab settings. Its Class ZZ Plus classification makes it appropriate for inspection of commercial-grade work where repeatable, traceable measurements are required. Each unit ships with a Certificate of Accuracy with NIST Traceability, supporting documented quality management systems and audit requirements. It is applicable in light manufacturing, precision machining shops, and any setting where dimensional hole inspection is part of standard quality control workflow.

Key Features

• Class ZZ Plus tolerance class for commercial and inspection-grade Go gauging
• 0.2745 inch measurement diameter with 0.0002 inch tolerance
• 10 microfinish surface for accurate, low-friction contact during inspection
• Tool steel construction for wear resistance and long service life
• Includes Certificate of Accuracy with NIST Traceability for quality system compliance
• Conforms to ASME B89.1 standards

Compatibility

Designed for Go inspection use with setting micrometers, verniers, and other precision measuring devices where a 0.2745 inch diameter plug gage is required per ASME B89.1.

Installation Notes

Plug gages are handled and used by quality control technicians and machinists — no power tools or electrical shutoff is required. Store the gage in a clean, dry environment and handle it with lint-free gloves to prevent corrosion from skin oils. Do not force the gage into a bore; light, consistent hand pressure is the correct technique. Inspect the gage surface periodically for wear or damage that could affect measurement accuracy.
