The "Nord-Lock Stainless Washer" is a product made from EN 1.4404 or equivalent material, with a surface hardening treatment. EN 1.4404 is austenitic chromium-nickel stainless steel containing molybdenum, and it is a stainless steel with a very low carbon content to reduce the risk of chromium carbide precipitation. EN 1.4404 is one of the most commonly used stainless steels, and Nord-Lock washers made from EN 1.4404 are suitable for most applications that are not exposed to chlorides or acidic environments. 【Features】 ■ Made from very low carbon content stainless steel (EN 1.4404) ■ Suitable for most applications that are not exposed to chlorides or acidic environments *For more details, please refer to the PDF document or feel free to contact us.

Our company handles the "Nord-Lock Washer," a type of locking washer. Utilizing a wedge-shaped cam, it relies on tension rather than friction resistance. We offer SC materials (M3 to M130) and SUS materials (M3 to M80), as well as our new product, the Nord-Lock Washer X series. Individual sales are also available! This product is useful when true safety in bolt fastening is required. 【Features】 ■ Maintains high axial force, ensuring reliable fastening function ■ Quick and easy installation and removal with standard tools ■ Allows the use of lubricants on the fastening body since it does not rely on friction ■ Achieves more precise axial force management due to clear and consistent friction conditions ■ Can be used under the same temperature conditions as standard bolts/nuts, etc. *For more details, please download the PDF or feel free to contact us.
