Nord-Lock X-series washers are innovative multifunctional locking washers that combine proven wedge-locking technology with intelligent settlement compensation—offering a complete solution for securing bolted joints under extreme conditions. Engineered for critical applications, these advanced vibration-resistant washers are designed to eliminate both bolt loosening and preload loss, providing unmatched safety and reliability.

Utilizing a unique conical shape, Nord-Lock X-series washers compensate for slackening caused by material settlements and surface roughness. At the same time, the patented wedge-locking effect ensures that any rotational movement results in increased tension, effectively locking the joint—even under severe vibration and dynamic loads.

Ideal for steel structures, heavy machinery, construction equipment, railway systems, wind turbines, and oil & gas applications, these high-performance self-locking washers help prevent costly failures and reduce maintenance intervals. The Nord-Lock X-series supports bolt grades up to 12.9, resists harsh environments with superior corrosion protection, and is easy to install and reusable without loss of function.

If you’re looking for a reliable, efficient, and technically advanced solution to secure bolted assemblies, the Nord-Lock X-series wedge-locking washers are your trusted choice for both bolt security and long-term preload retention.
