Nord Lock Washer is a specialized safety washer designed to provide secure bolt locking using tension instead of friction. It features a unique wedge-locking principle, where the washer pairs have cams on one side and radial teeth on the opposite side. When a bolt or nut is tightened, the cams on the washers engage, increasing the tension and preventing loosening caused by vibration and dynamic loads. This makes the Nord Lock Washer an ideal solution for critical engineering applications where safety and reliability are paramount. Its durable steel construction ensures resistance to corrosion and mechanical stress. Used across industries such as construction, heavy machinery, automotive, and aerospace, Nord Lock Washers are essential components for maintaining bolt integrity in demanding conditions.

Nord Lock Washer uses a unique wedge-locking mechanism where cams on one side of the washer pair interact with radial teeth on the opposite side. When tightened, this design increases bolt tension and prevents loosening due to vibration or dynamic forces, unlike conventional washers that rely on friction alone.
Yes, Nord Lock Washers can be removed and reused without loss of their locking capability, provided they are not damaged during removal.
Nord Lock Washers are generally made from high-grade steel such as C45 and come with coatings like zinc plating or stainless steel options to ensure resistance against corrosion and mechanical wear.
These washers typically operate efficiently in temperature ranges from -40°C to +120°C, making them suitable for most industrial applications involving heat exposure within this range.
Nord Lock Washers are widely used in automotive manufacturing, heavy construction equipment, aerospace engineering, renewable energy installations, and other industrial machinery sectors where bolt safety is critical.
