        Fasteners form the integrating elements of any aerospace hardware and provide the required mechanical integrity. Various types of fasteners including screws, rivets, bolts, pins, blind rivets, blind bolts, anchor nuts, solid inserts, collars etc. are used in aerospace application. Aerospace fasteners needs to be more durable, lighter and shall withstand high loads, vibrations and hostile environments such as deep space etc. In order to achieve this, aerospace fasteners are processed through specialized forging, heat treatment and thread rolling. Finite element analysis is done simulating the tensile testing of slotted counter sunk head screws and experiments are also conducted to verify the analysis results. A comparison is made on the stress distribution contours of slotted 120 degree countersunk head screw and slotted 90 degree countersunk head screw.
