The DIN 9021-M5-A2 is a metric fender washer designed for M5 fasteners in aerospace assemblies. Manufactured from A2 stainless steel to DIN 9021 specifications, this washer provides a wide bearing surface that distributes clamping loads across thin panels and composite materials. Installation places it under the bolt head or nut to prevent fastener pull-through during assembly.

The expanded diameter accommodates low-strength substrates where standard washers would sink into the surface. Verify torque specifications and hardware compatibility with applicable maintenance documentation before installation.
