In many structures and machines, screws and their connections play a key role. However, tightening alone often does not guarantee durability and safety, especially when components are exposed to vibration, dynamic loads, or changing operating conditions. Nord-Lock self-locking washers — a solution that secures screw connections much more effectively than classic washers.
What are Nord-Lock washers?
Nord-Lock washers are special self-locking locking washers, which, thanks to their unique design, protect screw connections against unintentional loosening. Instead of relying on friction, Nord-Lock technology uses mechanical wedging effect: when the screw is tightened, special protrusions and grooves in the washers block the rotational movement, so the connection remains durable even under high vibrations and load changes.
Why use Nord-Lock washers?
1. Effective protection against loosening
- Thanks to the wedging mechanism, Nord-Lock washers maintain the clamping force of the connection even under conditions of strong vibrations and dynamic loads that could cause a classic screw to loosen.
2. Lubrication does not affect the wedging function
- Their performance is independent of friction and lubrication conditions, ensuring stability in a variety of applications and operating environments.
3. Wide range of applications
- Nord-Lock washers are available in various materials (e.g. hardened steel, stainless steel) and sizes, making them suitable for use in steel structures, industrial machinery, photovoltaics, flange connections, and even in the automotive and railway industries.
