Webb9 apr. 2024 · 16. Shoulder Bolts. A shoulder screw, also known as a shoulder bolt, has a shank with a larger diameter immediately below the head, which “steps down” down to a smaller diameter for the length of the thread. The change in diameter creates a “shoulder” that can be tightened firmly against the screwed-on part. WebbDue 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 =.
