Insize Metric fine Thread Plug Gages 4139

Insize Metric Fine Thread Plug Gages 4139 are precision tools used to inspect the pitch diameter and the functional thread of internal threaded holes. They are designed to check the accuracy and conformity of metric fine threads, ensuring that they meet the required specifications. These plug gages are made from high-quality alloy steel, providing durability and accuracy in measurement.

The gages feature a double-ended design, with each end having a different thread size. One end is used for GO (to check the minimum diameter of the hole) and the other for NO-GO (to check the maximum diameter of the hole). The GO end should fully enter the threaded hole, while the NO-GO end should not.

Insize Metric Fine Thread Plug Gages 4139 are essential tools in industries such as automotive, aerospace, and manufacturing, where precision threading is critical. They help ensure that threaded components fit together properly, reducing the risk of thread damage and ensuring the overall quality of the final product.
