Abstract
An exemplary fastener used for connecting at least two components together includes a bolt, a shell, and an elastic member. The bolt has a head, a shaft, an engaging portion, and a threaded portion in series. A diameter of the engaging portion is larger than a diameter of the shaft and a diameter of the threaded portion. The shell has a side wall and a collar extending inwardly from a bottom of the side wall. The collar defines a through hole therein. A diameter of the through hole is slightly smaller than the diameter of the engaging portion of the bolt. The elastic member is sandwiched between the head of the bolt and the collar of the shell. The bolt with the elastic member is received in the shell, and a top of the engaging portion of the bolt abuts against a bottom of the collar of the shell.
