  • Fastener and method for reducing stress failure in an engine component
    Patent number: 7341414
    Abstract: A fastener and a method for reducing stress failure in a fastening joint of an internal combustion engine component are provided. The threaded fastener may be a bolt or a stud secured to an engine block. The fastener has a threaded tip portion with a radius and a distal end. The threaded tip portion is inserted into a threaded hole to define a threaded interface. In one embodiment, the load carrying capability is increased by progressively reducing the radius of at least a part of the threaded tip portion. In another embodiment, the load carrying capability is increased by an axially extending hole at the distal end of the threaded tip portion, the hole having a progressively reduced diameter.
