Vermont Gage 111310550 Class Zz Plus Plug Gage 0.1055in

Product Description

The VERMONT GAGE 111310550 is a Class ZZ Plus plug gage ground to a 0.1055-inch diameter with a tolerance of 0.0002 inches and a 10 microfinish surface. It is used to verify bore dimensions in precision machining and inspection environments. The gage is manufactured from tool steel for durability and dimensional stability. Each unit ships with a Certificate of Accuracy traceable to NIST, confirming it meets ASME B89.1 standards. Machinists, quality control technicians, and metrology professionals install and use this gage as part of go/no-go inspection routines or for calibrating and verifying micrometers, verniers, and other measuring devices.

This plug gage is suited for go inspection applications in production and quality assurance settings. It is sized for small-bore work at 0.1055 inches and is appropriate for use in job shops, manufacturing facilities, and metrology labs where tight dimensional tolerances must be verified. It serves as a reliable reference standard when setting or checking micrometers, vernier calipers, and similar measuring instruments. Overall length is 2.0 inches, making it easy to handle in confined inspection setups.

Key Features

• Class ZZ Plus tolerance class with 0.0002-inch tolerance for precise bore verification
• 10 microfinish surface for accurate, repeatable contact measurement
• Tool steel construction for long service life and dimensional stability
• Includes Certificate of Accuracy with NIST traceability
• Conforms to ASME B89.1 standards
• Compact 2.0-inch overall length for easy handling in small-bore inspection

Compatibility

Designed for use as a go inspection gage and for setting and verifying micrometers, verniers, and other precision measuring devices where a 0.1055-inch reference diameter is required.

Installation Notes

Handle plug gages with clean, dry hands or cotton gloves to prevent corrosion from skin oils. Store the gage in its protective case when not in use and allow it to reach ambient temperature before taking measurements. Periodic cleaning and re-verification against a NIST-traceable standard is recommended to maintain accuracy over time.
