Vermont Gage 111188000 Class Zz Plus Plug Gage 0.88 in

Product Description

The VERMONT GAGE 111188000 is a Class ZZ Plus plug gage machined from tool steel for precise go-type dimensional inspection. It measures a nominal diameter of 0.88 inches with a tolerance of 0.0002 inches, making it suitable for verifying bore and hole dimensions to tight manufacturing specifications. The gage carries a 10 microinch surface finish and ships with a Certificate of Accuracy traceable to NIST. Dimensional inspection technicians, machinists, and quality control personnel use this plug gage to confirm that manufactured parts fall within acceptable limits before assembly or shipment.

This plug gage is used in go inspection applications where a machined bore or hole must be verified against a minimum acceptable diameter. It is also used as a reference standard for setting micrometers, vernier calipers, and other measuring devices in shop and laboratory environments. The 0.88-inch diameter makes it applicable to a wide range of precision machined components across manufacturing, tooling, and metrology setups. Overall length is 2.0 inches, keeping it compact and easy to handle during inspection routines.

Key Features

• Class ZZ Plus tolerance grade with 0.0002-inch tolerance for reliable go inspection
• 10 microinch surface finish for consistent and repeatable gage contact
• Tool steel construction for durability and wear resistance in production environments
• Includes Certificate of Accuracy with NIST traceability, supporting audit and calibration records
• Conforms to ASME B89.1 standard for dimensional gages
• Compatible with use as a setting reference for micrometers, verniers, and other measuring devices

Compatibility

Designed for go inspection of bores and holes at 0.88-inch nominal diameter. Also suitable for setting and calibrating micrometers, vernier calipers, and other measuring devices requiring a traceable dimensional reference at this diameter.

Installation Notes

This gage is handled and used by metrology technicians, machinists, and quality control inspectors. Store and transport in a protective case to prevent surface damage to the gage member. Clean the gage and the bore being measured before use to avoid false readings caused by debris or residual cutting fluid. Do not force the gage into an undersized bore, as this can damage both the gage and the workpiece.
