Vermont Gage 112409150 Class Zz Minus Plug Pin Gage 9.15 Mm

Product Description

The VERMONT GAGE 112409150 is a Class ZZ Minus plug pin gage machined from steel for NoGo inspection applications. It measures 9.15 mm in diameter with a tolerance of 0.00508 mm, making it suitable for verifying that a bore or hole does not exceed its maximum allowable size. The gage is 2 inches in overall length and carries a Certificate of Accuracy with NIST traceability, confirming that each unit has been verified against a national measurement standard. Machinists, quality technicians, and metrology professionals use this type of gage as part of go/no-go inspection routines on production floors and in inspection labs.

This plug pin gage is used in dimensional inspection setups where a NoGo member is required to confirm upper-limit compliance on a hole or bore. Typical applications include setup verification for micrometers, vernier calipers, and other measuring devices, as well as inline quality checks during machining operations. The 9.15 mm diameter fits into inspection programs for metric-dimensioned workpieces in both light manufacturing and precision machining environments. It is appropriate for residential shop, commercial, and industrial inspection use wherever metric tolerance control is required.

Key Features

• Class ZZ Minus designation for NoGo inspection - confirms hole does not exceed maximum allowable size
• 0.00508 mm tolerance for precise dimensional verification
• Steel construction with 10 microfinish surface coating for dimensional stability and wear resistance
• Includes Certificate of Accuracy with NIST traceability
• 2 inches overall length for easy handling in standard gage holders
• Compatible with micrometers, verniers, and other measuring devices for setup and calibration use

Compatibility

Designed for use with micrometers, vernier calipers, and other measuring devices requiring a Class ZZ Minus NoGo plug gage reference at 9.15 mm diameter.

Installation Notes

Plug pin gages are handled and used by quality technicians and metrology personnel - no power tools or trade licensing is required, but proper gage handling practices apply. Always clean the gage and the workpiece bore before use to prevent false readings caused by debris or oil buildup. Store the gage in its protective case when not in use to avoid surface damage that could affect dimensional accuracy. Do not force the gage into a bore; if resistance is encountered on a NoGo member, the inspection result is valid and forcing will damage the gage surface finish.
