MTU 28209940515/0 is a tab washer manufactured by MTU.
A tab washer is a special type of washer, typically featuring one or more tabs or projections. These tabs can be bent to form a mechanical lock, which prevents nuts and bolts from rotating in mechanical applications and ensures the safety of secured connections. This kind of washer is widely used in industries such as automotive, aerospace, and industrial machinery—especially in working conditions where vibrations, rotational forces, or environmental stresses may threaten the integrity of fastener connections.
