We have released a product video for the TM-320 series retaining washers on YouTube. ■Features This washer provides a retaining effect by being pressed onto the tips of screws and bolts after panel insertion. The claws fit with the screw section, demonstrating a strong effect. Once installed, the washer cannot be removed without destruction, ensuring a robust retention of screws and bolts. For equipment and devices exported to EU member countries, it is recommended by the Machinery Directive within the CE regulations that bolts do not fall off when removing covers. This washer is suitable for that purpose, as it does not come loose due to vibrations during transport, ensuring safety. We offer five sizes: M3, M4, M5, M6, and M8, making it suitable for a wide range of screws and bolts. If you require other sizes, please consult with our representative. Made of stainless steel, it can be used in areas exposed to water and outdoors.

We have released the 【Supplementary Catalog】 2025 TOCHIGIYA INDEX & Examples of Use.
