Overview
Advanced Wedge-Locking Technology
Nord-Lock 254 SMO Locking Washers are engineered to help prevent bolted joints from loosening when exposed to vibration and dynamic loads. The Nord-Lock wedge-locking principle secures the joint through tension rather than relying solely on friction, helping maintain bolt preload during demanding operating conditions.
254 SMO Stainless Steel Construction
Manufactured from 254 SMO stainless steel, these locking washers are designed for applications requiring a high level of corrosion resistance. 254 SMO is a high-alloy austenitic stainless steel developed for demanding environments, making it an appropriate material choice where conventional stainless steel fastening components may not provide the required resistance to aggressive conditions.
Designed for Aggressive Environments
Nord-Lock 254 SMO Locking Washers are particularly suited to applications where fastening components may be exposed to moisture, chlorides, seawater, or corrosive process environments. Their material selection provides an additional level of environmental resistance while retaining the mechanical locking characteristics of the Nord-Lock system.
Secure Bolted-Joint Performance
The wedge-locking system is designed to maintain the integrity of threaded connections subjected to vibration and dynamic loading. By increasing tension within the joint when loosening begins, the washer system helps protect against unintended rotation of the bolt or nut.
Pre-Assembled Washer Pairs
Nord-Lock locking washers are supplied as pre-assembled pairs, helping simplify handling and installation. The washer pair is positioned beneath the bolt head or nut, providing a straightforward installation method for securing threaded connections in industrial assemblies.
For Critical Industrial Applications
The combination of 254 SMO stainless steel and wedge-locking technology makes these washers suitable for applications where both corrosion resistance and bolted-joint security are important. They can be used in demanding industrial environments where equipment reliability and fastening integrity are essential considerations.
Applications
Nord-Lock 254 SMO Locking Washers are suitable for demanding applications including marine and offshore equipment, chemical processing systems, desalination and water treatment equipment, pumps and valves, power generation equipment, process machinery, and other installations exposed to aggressive or corrosive environments.
Nord-Lock Engineering
Nord-Lock has engineered its wedge-locking system specifically for securing bolted joints against loosening caused by vibration and dynamic loads. The 254 SMO series combines this established mechanical locking principle with a high-performance stainless steel material for applications where corrosion resistance is a critical consideration.
