Product Description
The b0203011-4 is a hexagonal castellated nut designed to accept a cotter pin for positive mechanical locking on aircraft hardware. Constructed from steel and conforming to Aeronautical Standard AN310/AN320 specifications, this nut threads onto drilled-shank bolts in aviation assemblies where vibration-resistant fastening is critical. The castellated design features radial slots that align with the bolt's drilled hole, allowing a cotter pin to pass through and lock the nut permanently in position.
Installation requires proper torque sequencing and cotter pin placement per AC 43.13-1B or the applicable aircraft maintenance manual to ensure airworthiness.
