Nord-Lock Steel Construction (SC) washers are specialized wedge-locking washers engineered specifically for steel construction applications, ensuring maximum safety and joint integrity in structural bolted connections. Designed in full compliance with European standards EN 14399-3, EN 14399-4, and EN 14399-8, these washers provide reliable performance for high-strength structural bolting assemblies.

The Nord-Lock SC washers utilize a proven wedge-locking mechanism that prevents bolt loosening under dynamic loads, intense vibration, and heavy preload conditions common in steel construction. By creating a wedge effect between the washer cams, they effectively secure bolted joints and maintain tension over time, reducing the risk of structural failure and minimizing maintenance.

Ideal for bridges, buildings, towers, and other civil engineering structures, Nord-Lock SC washers are the preferred choice for engineers and contractors seeking vibration-resistant, high-performance locking washers that meet strict industry standards.
