Abstract

Threaded fastener is widely used in industrial and household applications. It retains good amount of tightening load and also offers easy assembling and disassembling. However, it can be loosened under vibration thereby causing fatal mishaps sometimes. In the present experimental investigation, a comparative study of the anti-loosening tendency of various high tension steel M14 threaded fasteners is evaluated on an indigenously made testing rig offering accelerated test facility. It is observed that the decrease in clamping force is the lowest after 12600 oscillations for nylon wrapped bolt. Hybrid double nut is found to show good resistance to loosening next to nylon wrapped bolt.
