Flat serrated chain links, also known as flat sawtooth links or flat type connectors, are used to connect mining chains, particularly those in conveyor systems. These links are designed to be easily assembled and disassembled, with different tooth shapes (sawtooth, ladder, arc) affecting the ease of connection and disconnection. They are commonly used to connect round link chains in both horizontal and vertical positions, according to DIN 22252.
