Black Coupling: 1/4" MPN:13310

Class ZZ Plus Plug Gage, with a diameter of 11.32mm, is a premium precision gauge used for verifying the dimension or alignment of a bore during production. This plug gage is specifically designed for applications that require tight tolerances and extreme accuracy in measuring cylindrical parts such as engine blocks, ball bearings, and pistons. Made from high-quality steel materials and finished to an RA 0.8 surface finish, it provides exceptional reliability with minimal wear or distortion over time. Class ZZ Plus Plug Gage can also be used as a form or go/no-go gauge for inspecting internal diameters in production, ensuring consistent quality control across multiple operations and preventing costly reworks.
