Abstract

A Grub screw is a type of screw generally used to lock an object within or against another object. These screws are headless and mainly used in all types of gears and shaft. The following work is based on optimization of the strength of flat slotted screw head with different slot shapes. In the paper, we have considered samples of 3 different slotted flat headed grub screw profile with their corresponding screwdriver profile. The aim was to obtain the maximum torque handling capacity among the identified slot shapes. An iterative process involving design upgradation and finite element analysis was carried out. For this purpose validation of the FEA was performed by torsion testing of the specimen in the torsion testing machine.The results showed that 17° slotted angle grub screw gives better torque handling capacity than 0° slot angle. The study shows that a variation in the slot shape of a grub screw can influence the torque handling capacity.
