DIN128A Stainless Steel Curved Spring Lock Washers
Curved spring lock washers are essential fastening components in dynamic and load-bearing assemblies, ensuring that connections remain tight and secure even in environments subjected to constant vibration and thermal expansion. Curved Spring Lock Washers are specifically designed to provide axial flexibility and resistance to loosening, making them indispensable in various industries.
At Flybear Fastener, we supply high-quality DIN128A curved spring lock washers made from premium stainless steel to meet the highest global standards for durability, corrosion resistance, and performance.
Product Overview
Curved spring lock washers, also known as crescent washers, are designed to introduce a spring force between the fastener head and the substrate to maintain preload and prevent loosening. The DIN128A standard defines their dimensions and mechanical properties, ensuring consistent performance across applications.
These washers are widely used in assemblies subjected to dynamic loads or frequent temperature changes, where bolt self-loosening is a concern.
