Why Does Self Clinching Nuts Rust And How To Improve It?

The rust of Self Clinching Nuts is the result of an oxidation reaction on the surface due to long-term exposure to moisture or air. Rusty nuts can cause problems such as inconvenient use and reduced tightening force, so timely measures need to be taken to improve them. Here are some possible approaches:

Clean and lubricate. First, the rusty nuts need to be cleaned. You can use a soft brush or eraser to remove rust on the surface. Then, apply a layer of lubricating oil or anti-rust agent on the surface of the nut to prevent the nut from rusting again.

Pickling treatment. If the nut is seriously rusted, pickling can be used. Put the nut into a container filled with acidic solution, the acidic solution can remove the oxide layer on the surface of the nut to achieve the effect of rust removal. However, it should be noted that the pickling operation is more dangerous, and it is necessary to wear protective gloves, glasses and other protective equipment to avoid contact with acidic solutions.

Replace the nut. If the nut self clinching fasteners are seriously rusted or have a long service life, it is recommended to replace the new nut directly. The surface of the new nut is smooth, no rust, and the service life is relatively long.

Improve the storage environment. In order to avoid the nut from rusting, the storage environment can be improved. For example, put some moisture-proof agent, desiccant and other items in the container for storing nuts to keep the storage environment dry. Alternatively, store the nuts in an airtight container, out of exposure to the air.

In general, in addition to disposing of rusted nuts in a timely manner, precautions should also be taken to prevent nuts from rusting. Keeping the surface of the nut dry and clean is the key to preventing the nut from rusting, and it is also necessary to pay attention to the environmental conditions during storage. Self-clinching nuts, also known as press-in nuts or Rivet Nuts, are fasteners designed for permanent installation in a sheet metal or panel. Self Clinching Nuts are commonly used in industries such as electronics, automotive and sheet metal fabrication.
