While a wide variety of loading profiles can cause fastener loosening, it is understood forces which lead to slipping of the clamped parts relative to one another will cause the most dramatic losses. The force that resists loosening is generated by friction between the mating threads and the bolt or nut and the mating part. In the standard bolted joint this resisting force is directly proportional to bolt tension – the greater the elongation of the bolt, the greater the friction force available to resist loosening. Because resistance to loosening decreased bolt elongation, the common occurrence of joint relaxation due to embedment within the joint stack will leave the joint more susceptible to loosening. The following flowchart identifies these three primary means of preventing threaded fastener loosening and lists specific remedies under each of the three headings.
