Split Lock Washers

Split lock washers are hardware components designed to prevent fasteners, like bolts and nuts, from unintentional loosening due to vibrations or dynamic loads. Characterized by a split cut, they feature two ends bent slightly outward, creating a spring-like effect. When installed, the washer exerts a constant radial force against the fastener, promoting friction and resisting rotational movement. This helps maintain a secure and stable connection in various applications, such as machinery and automotive assemblies. However, their effectiveness has been debated, and alternative methods, like nylon-insert lock nuts or thread-locking adhesives, are sometimes preferred for better reliability in specific environments.
