Tension capacity of m20 bolt
Did you know?
WebDue to preload uncertainty, the actual preload applied to the bolt may be more or less than the nominal value. Due to preload relaxation, there will be some loss in the preload after the joint is installed. The maximum value of preload accounts for the preload uncertainty, and is calculated as: F PL.max = (1 + % uncrt ) · F PL.nom =.
