Analysis of Slotted Counter Sunk (35NCD16 Steel) Aerospace Fasteners
Keywords: fasteners; aerospace; countersunk; screws; stress distribution; finite element analysis;
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.
