Spring Lock Washer (DIN 127 / ISO 7089)
The Spring Lock Washer, also known as a split washer, features an open and elastic structure. When tightened with bolts or nuts, it generates continuous spring pressure that enhances fastening stability and prevents loosening. With its simple structure and cost-effectiveness, it is one of the most commonly used anti-loosening solutions.
