Each Nord‑Lock washer comes with full traceability and is laser‑marked with the Nord‑Lock brand name, control number, and type code, allowing you to track the product right back to the first assembly.

Tension makes the bolt self‑locking

Need a washer that secures bolted joints exposed to severe vibrations and dynamic loads? Nord‑Lock created the original wedge‑locking technology, making it impossible for their products to loosen unintentionally thanks to the wedge formed under the bolt head and nut.

Nord‑Lock wedge‑locking washers are a high‑quality solution that meet ISO 9001 and ISO 14001 standards, and they carry certifications from BIBt (Deutsches Institut für Bautechnik), DNV (Det Norske Veritas), EBA (Eisenbahn‑Bundesamt), and TÜV (Technischer Überwachungs‑Verein).
