Vermont Gage 111118100 Class Zz Plus Plug Gage 0.181 in

Product Description

The VERMONT GAGE 111118100 is a Class ZZ Plus plug gage designed for precise go inspection of machined bores and holes at 0.181 inches in diameter. Built from tool steel with a 10 microfinish surface, this gage delivers a tolerance of 0.0002 inches, making it suitable for applications where dimensional accuracy is critical. At 2.0 inches in overall length, it is a compact single-member gage used by machinists, quality control technicians, and tool room professionals to verify that a drilled or reamed hole meets its minimum acceptable size. Each unit ships with a Certificate of Accuracy traceable to NIST, confirming compliance with ASME B89.1 standards.

This plug gage is used in manufacturing and inspection environments wherever go-type attribute gaging is required. Typical applications include verifying bore size on machined components during in-process or final inspection. It is also suited for setting and checking micrometers, verniers, and other measuring devices that require a known reference standard. Commonly found in tool rooms, quality labs, and production floors across metalworking, aerospace, automotive, and general machining operations.

Key Features

• 0.181 inch measurement diameter in tool steel construction
• 10 microfinish surface for consistent, repeatable gage contact
• Meets ASME B89.1 dimensional gage standards
• Includes Certificate of Accuracy with NIST traceability
• Compact 2.0 inch overall length for easy handling in tight inspection setups

Compatibility

Designed for go inspection of 0.181 inch diameter bores and as a reference standard for setting micrometers, verniers, and other precision measuring devices.

Installation Notes

Plug gages are handled and used by quality technicians and machinists and do not require installation in the traditional sense. Store the gage in its protective case when not in use to prevent surface damage and corrosion. Clean the gage and the bore being checked before use to ensure accurate readings and to protect the 10 microfinish surface. Handle with care to avoid dropping, as impact damage can alter the gage diameter and invalidate its calibration.
