What is a Forged Threaded / Screwed Square Plug?

A forged threaded or screwed square plug is a mechanical fitting used to seal the end of pipes, valves, or equipment openings. The square head makes it easy to install and remove using standard tools. These plugs are durable, easy to maintain, and can withstand high pressures and temperatures, making them ideal for critical applications.
