Vermont Gage 911102700 Class Zz Plus Plug Gage 0.027 in

Product Description

The VERMONT GAGE 911102700 is a Class ZZ Plus plug gage designed for precision go inspection of hole diameters at 0.027 inches. Manufactured from tool steel with a black oxide finish, this gage provides a tolerance of 0.0002 inches, making it suitable for accurate dimensional verification in machining and quality control environments. Each unit ships with a Certificate of Accuracy traceable to NIST, confirming conformance to ASME B89.1 standards. Machinists, quality technicians, and metrology professionals rely on this style of plug gage for repeatable, traceable inspection results.

This plug gage is used in go inspection applications to verify that a drilled, reamed, or bored hole falls within the specified tolerance range. With an overall length of 2 inches, it handles typical bench and in-process inspection tasks on production parts. It is also suited for setting and verifying micrometers, verniers, and other measuring devices where a known reference standard is required. Appropriate for both light manufacturing and precision machining environments.

Key Features

• Class ZZ Plus tolerance rating for go inspection applications
• 0.0002 inch tolerance for precise dimensional control
• Tool steel construction for durability and dimensional stability
• Black oxide finish resists corrosion and reduces glare during use
• Includes Certificate of Accuracy with NIST traceability
• Conforms to ASME B89.1 gage standards

Compatibility

Designed for go inspection of 0.027 inch diameter holes and for use as a reference standard when setting micrometers, verniers, and other measuring devices.

Installation Notes

Plug gages should be handled with clean, dry hands or inspection gloves to prevent corrosion from skin contact. Store in a protective case away from other tooling to avoid surface damage that could affect measurement accuracy. Clean the gage and the part to be inspected before use to remove chips, oils, or debris. Periodic recalibration against a certified standard is recommended to maintain traceability.
