Pin, Plug & Ring Gauges

0 products

Pin, plug, and ring gauges are precision tools designed to verify the dimensional accuracy of plain and threaded components, ensuring they fall within specified tolerance limits. Plain gauges assess the size of smooth holes and bores, while threaded plug gauges evaluate internal threads on parts and pipes. Threaded ring gauges are used for checking external threads. The Go/No-Go system, including Plus/Minus gauges, efficiently tests the tolerance range of both smooth and threaded components. Specialized gauges like L-1, L-2, L-3, and 6-step are employed for tapered pipe threads, ensuring comprehensive quality control across various applications.
