Abstract
A weld stud including a shank that has a reduced diameter portion, and a larger diameter portion. A weld base is defined on the reduced diameter portion and a flange is positioned on the larger diameter portion. A bore wall extends axially through a face of the flange and into the larger diameter portion. The bore wall has a threaded portion that has a threaded diameter for receiving a fastener. A base diameter of the weld base is smaller than a larger diameter of the larger diameter portion and substantially equal to, or smaller than the threaded diameter. The threaded portion is axially spaced from the face of the flange by a first unthreaded portion, which defines a first unthreaded diameter that is larger than the threaded diameter. These features limit the loads transmitted to the fastener, thus allowing the weld stud to withstand shock loads to prevent fastener failures.
