Vermont Gage 111123800 Class Zz Plus Plug Gage 0.238 in

Product Description

The VERMONT GAGE 111123800 is a Class ZZ Plus plug gage designed for precision inspection of hole diameters in manufacturing and quality control environments. Machined from tool steel and finished to a 10 microfinish surface quality, this gage measures a nominal diameter of 0.238 inches with a tolerance of 0.0002 inches. It conforms to ASME B89.1 standards and ships with a Certificate of Accuracy traceable to NIST. Machinists, toolroom technicians, and quality inspectors use plug gages like this one to verify bore diameters quickly and reliably on the shop floor or in an inspection lab.

The 111123800 is suited for Go inspection of holes at 0.238 inches diameter across a range of applications including setting micrometers, verniers, and other precision measuring devices. At an overall length of 2.0 inches, it fits comfortably in standard gage handle assemblies used in both production line inspection and toolroom calibration work. It is appropriate for both high-volume manufacturing verification and low-volume precision part inspection in industrial, aerospace, and general machining environments.

Compatibility

Designed for use with standard plug gage handles and suitable for Go inspection applications, setting micrometers, verniers, and other precision measuring devices requiring a 0.238-inch reference diameter.

Installation Notes

Plug gages are installed and used by quality technicians and toolroom machinists following standard metrology practices. Handle the gage with clean, dry hands or lint-free gloves to prevent surface corrosion and measurement error. Store in a protective case away from temperature extremes to maintain dimensional stability. Always verify the gage is clean and free of debris before use to ensure accurate readings.
