Split Ring Lock Washers (also referred to as "Spring Lock Washers", or most simply "Lock Washers") are circular washers split at a certain point to create a helical shape. This shape applies force between the head of a bolt or screw and the installation surface. This force creates a resistance to rotation and prevents nuts, bolts and screws from vibrating loose.
Lock Washers in this selection have a silicon bronze finish.Silicon bronze fasteners are made of copper, silicon, and various other alloys such as zinc, tin, iron and manganese. Silicon bronze is used in marine environments, corrosive environments, and high heat environments. Often used in plumbing and electrical applications, silicon bronze fasteners are also found on tattoo machines and in power plants. Silicon bronze is similar in color to copper and is sometimes used in finish applications for the color.
