of achieving fastener initial preload always indicates

ABSTRACT

Use of torque as the sole means of achieving fastener initial preload always indicates that the person responsible for the specification has accepted the scatter in preload results that will naturally occur. It should also be recognized that torque tightening strategies are based on statistical variations of a known degree of scatter, and there is no provision to allow for problems introduced when parts with characteristics outside of the normal population show up on the assembly line.
