WebOct 2, 2024 · Defining Bolt Preload in Finite Element Simulations •In the real world, bolts are tightened by applying torque. •In real-life, tightening a bolt reduces its grip-length and produces tensile preload. •Applying torque and rotating the nut in a simulation is computationally expensive and does not add any value or accuracy to the results. WebJan 21, 2024 · @Ron- The shank length will vary a bit depending on the manufacturer and is not a black and white answer. ASME B18.21.1 which covers hex bolt dimensions, allows for up to 5 full coarse threads to extend into the grip length, so therefore the grip/thread length will vary depending on the diameter of the bolt, since five threads of 1/2-13 and …
