Insize Metric Fine Thread Plug Gage 4642

The Insize Metric Fine Thread Plug Gage 4642 is a precision measurement tool used to verify the accuracy and tolerances of internal threads in components such as nuts, threaded holes, and other threaded parts. This plug gage is specifically designed to check metric fine threads according to international standards such as ISO, DIN, or ANSI, ensuring that threaded components meet required specifications and tolerances.One of the primary functions of the Insize Metric Fine Thread Plug Gage 4642 is to verify the pitch diameter and thread form of metric fine threads with high precision. The gage is manufactured with strict adherence to standard thread specifications, ensuring accuracy and reliability in its measurements.The plug gage is designed to be inserted into the threaded hole or nut being tested, and it should fit smoothly and snugly without excessive play if the internal threads are within the specified tolerance range. The gage is labeled as a "go" gage, indicating that it checks for proper thread fitment within acceptable limits.The Insize Metric Fine Thread Plug Gage 4642 is available in various metric thread sizes and pitches to accommodate different applications and requirements. It is commonly used in industries such as automotive, aerospace, machinery manufacturing, and precision engineering, where accurate thread measurements are critical for ensuring the functionality, safety, and reliability of threaded assemblies.These plug gages are precision-manufactured from hardened steel or similar durable materials to withstand repeated use and maintain their accuracy over time. They may also feature a protective coating or finish to enhance corrosion resistance and prolong their lifespan in various working environments.In summary, the Insize Metric Fine Thread Plug Gage 4642 is an essential tool for verifying the accuracy and tolerances of metric fine threads in internal threaded components, contributing to the overall quality and reliability of manufactured products that rely on precise thread fitment.
