[VA/VE Case] Proposal for Additional Circulation Holes in the Plated Bag Hole Male Thread Section to Suppress Rust

We will introduce a case where the rust problem inside the menegis due to the passage of time has been resolved!

Here is an example of a product made from iron-based material with a threaded hole processed on the end face, which undergoes a plating process. When immersed in the liquid, the interior of the bag-shaped threaded hole becomes an air pocket, preventing the plating solution from circulating, resulting in a thin film forming inside. In such cases, due to insufficient plating, rust begins to develop from the back of the thread over time. By drilling through the pilot hole of the bag-shaped threaded hole at a 90° angle, air pockets are eliminated in the threaded section, allowing the plating solution to circulate. This not only ensures proper plating inside the threads but also suppresses rust formation over time. [Issues] - When immersed in the liquid, the interior of the bag-shaped threaded hole becomes an air pocket, preventing the plating solution from circulating, resulting in a thin film forming inside. - Due to insufficient plating, rust begins to develop from the back of the thread over time. *For more details, please visit our website or feel free to contact us.*
