Vermont Gage 112309290 Class Zz Plus Plug Gage 9.29 Mm

Product Description

The VERMONT GAGE 112309290 is a Class ZZ Plus plug gage designed for dimensional inspection of holes and bores with a nominal diameter of 9.29 mm. Manufactured from tool steel with a 10 microfinish surface coating, it delivers the surface quality and hardness required for repeatable go-inspection use. The gage holds a tolerance of 0.00508 mm, meeting ASME B89.1 standards. Each unit ships with a Certificate of Accuracy traceable to NIST, making it suitable for quality-controlled environments. Metrology technicians, tool-and-die shops, and precision machinists use this gage in production and incoming inspection workflows.

This plug gage is used for go inspection of machined holes, bores, and threaded features requiring close dimensional control. At 9.29 mm diameter, it fits standard inspection routines alongside micrometers, verniers, and other measuring devices. The overall length of 2.0000 inches allows easy handling in both bench and floor-level inspection settings. It is appropriate for light industrial, aerospace, automotive, and general precision manufacturing environments where ASME B89.1 compliance is required.

Key Features

• Class ZZ Plus tolerance grade - 0.00508 mm tolerance per ASME B89.1
• Tool steel construction for hardness and wear resistance in repeated use
• 10 microfinish surface coating for consistent gage-to-bore contact
• NIST-traceable Certificate of Accuracy included with each unit
• Designed for go inspection applications with micrometers, verniers, and measuring devices
• Compact 2.0000-inch overall length for easy bench or in-process use

Compatibility

Designed for go inspection use with micrometers, verniers, and other measuring devices requiring a 9.29 mm reference diameter. Compatible with inspection routines governed by ASME B89.1.

Installation Notes

Plug gages are handled and used by metrology technicians and quality control personnel. Clean the gage and bore surface before use to remove chips, coolant, or debris that can affect readings. Do not force the gage into a bore; light hand pressure is sufficient for a go gage check. Store the gage in its protective case and apply a light coat of rust-preventive oil when not in use to preserve the surface finish and dimensional integrity.
