Nord-Lock Steel Construction (SC) washers are wedge-locking washers specially designed for use on steel construction applications in accordance with the European standard EN 14399-3 /EN 14399-4 /EN 14399-8. EN 1.4404 is an austenitic chromium-nickel stainless steel containing molybdenum. EN 1.4404 is one of the most commonly used stainless steel grades. This stainless steel also has extra-low carbon content in order to reduce the risk of chromium-carbide precipitation. Nord Lock washers made of EN 1.4404 are suitable for most applications where no chlorides or acids are present.
