Vermont Gage 112209380 Class Zz Minus Plug Pin Gage 9.38 Mm

Product Description

The VERMONT GAGE 112209380 is a Class ZZ Minus plug pin gage machined from steel for precision bore and hole inspection. It measures 9.38 mm in diameter with a tolerance of 0.00508 mm, making it suitable for NoGo inspection work where tight dimensional control is required. The gage ships with a Certificate of Accuracy traceable to NIST, confirming its calibration to a recognized national standard. Overall length is 2 inches. The 10 microfinish surface coating reduces wear and maintains measurement integrity over repeated use. Calibration professionals, quality technicians, and machinists rely on this type of gage for verifying hole dimensions in production and inspection environments.

This plug pin gage is intended for NoGo inspection applications, confirming that a bore or hole does not exceed the maximum allowable size. It is also used to set micrometers, verniers, and other measuring devices that require a known reference diameter. Typical environments include machine shops, metrology labs, and manufacturing quality-control stations where consistent hole-size verification is part of standard process control. The 9.38 mm diameter fits into inspection routines for small precision bores common in mechanical component manufacturing.

Key Features

• Class ZZ Minus tolerance class with 0.00508 mm tolerance for tight NoGo inspection work
• Steel construction with 10 microfinish surface for durability and consistent gaging accuracy
• Includes Certificate of Accuracy with NIST traceability for documented calibration
• 2-inch overall length for comfortable handling and access in standard inspection setups
• Suitable for setting micrometers, verniers, and other precision measuring devices

Compatibility

Designed as an OEM-style replacement and standard inspection tool for use in NoGo plug gage sets requiring a 9.38 mm diameter pin, and compatible with micrometer and vernier setting applications at that diameter.

Installation Notes

This gage is handled and used by quality technicians and metrology professionals; no power source or mechanical installation is required. Keep the gage clean and lightly oiled when stored to prevent corrosion on the steel body. Do not force the gage into a bore - if resistance is met, the hole is undersized and the gage should be withdrawn without torquing. Store in a protective case away from temperature extremes to preserve dimensional stability.
