High Strength Engineering Fasteners: Design for Fatigue Resistance

Technical Article---Peer-Reviewed

Abstract

One of the most frequently encountered causes of failure in engineering fasteners is fatigue. Typical locations for the fatigue of fasteners are the stress concentrations represented by the head to shank fillet, the first engaged thread and the thread runout. These locations are examined in relation to design rules known for over 60 years to be effective in reducing the stress concentration effect, but seldom used in engineering bolts, despite their relative simplicity. These design rules are also examined in relation to common fastener standards and their silence with regard to fatigue considerations.
