Precision instruments called Thread Plug Gauges are used to check that internal threads in machined objects are accurate and meet tolerance requirements. We provide a wide variety, such as Double Ended Thread Plug Gauges, which combine GO and NO-GO functions in a single tool for effective inspection, and Baker Plug Gauges, which are renowned for their longevity and great accuracy. These gauges are crucial for sectors including engineering, automotive, and aerospace and are perfect for quality control in manufacturing. Because every gauge is made in accordance with international standards, thread integrity and compliance can be checked consistently and reliably throughout production batches.
