Guide to bolted joints and screw threads data
Abstract:ESDU 14003 examines the relationships between the various Data Items which are relevant to the design of bolted joints that can be found in the Stress and Strength of Components Series. In this Item, the general function of a bolted joint and the role of pretension in securing the bolt is discussed. For bolted joints, design strategies are based, in the first instance, on the nature and magnitude of loads applied within the system. If a shear load is applied to the bolted joint then the phenomena of bolt self-loosening is likely to occur and this Item gives guidance on using lock nuts or other thread locking devices to maintain the contact between the parts of the bolted assembly and also to prevent unscrewing of the bolt threads. The behaviour of bolted joints in cases when a static or a fatigue load is applied to the bolted joint is also considered in this Item.
