A fastening system with a rotatable fastener that may secure an aircraft store to an aircraft and may rotate to reduce a drag coefficient of the aircraft store. Reducing the drag coefficient of the aircraft store may increase fuel efficiency of the aircraft store by requiring less energy to propel the aircraft store at a given speed or acceleration.The rotatable fastener allows the aircraft store to attach to the aircraft and to possess a low drag coefficient once the aircraft store is deployed. The rotatable fastener member may be configured to conform to attachment interface standards, such as Standardization Agreement (“STANAG”) 3842 or any other suitable aircraft store attachment interface standard.
