Vermont Gage 111132900 Class Zz Plus Plug Gage 0.329 in

Product Description

The VERMONT GAGE 111132900 is a Class ZZ Plus plug gage designed for go inspection applications in precision measurement environments. With a measurement diameter of 0.329 inches and a tolerance of 0.0002 inches, this plug gage delivers consistent, repeatable dimensional verification. The 10 microfinish surface on the gage member reduces wear and helps maintain accuracy over extended use cycles. Constructed from tool steel for durability, this gage is a standard instrument used by quality control technicians, machinists, and metrology professionals on the shop floor and in inspection departments.

This plug gage is suited for verifying hole diameters to tight tolerances in machined components. It is commonly used alongside set micrometers, verniers, and other precision measuring devices to confirm dimensional conformance. The go inspection function confirms that a bore or hole falls within the accepted minimum material condition. At 2.0 inches overall length, the 111132900 is a compact, handheld instrument appropriate for both production-floor and bench inspection use. It ships with a Certificate of Accuracy traceable to NIST, supporting quality management and documentation requirements.

Key Features

• 10 microfinish surface for reduced wear and consistent contact
• Tool steel construction for long-term durability in production environments
• Includes Certificate of Accuracy with NIST traceability for quality documentation
• Meets ASME B89.1 standards for plain plug gages
• Compact 2.0 inch overall length for easy handheld use

Compatibility

Designed for go inspection use with set micrometers, verniers, and other precision measuring devices as noted in the product specifications. Suitable for standard plain bore inspection applications requiring Class ZZ Plus tolerance plug gages per ASME B89.1.

Installation Notes

Plug gages are handled and used by quality control technicians and machinists. Keep the gage clean and lightly oiled when not in use to prevent corrosion on the tool steel surfaces. Never force the gage into a bore; apply only light, consistent hand pressure to avoid damaging the gage or the workpiece. Store in a protective case away from temperature extremes to maintain dimensional stability and NIST-traceable calibration integrity.
