- RB&W¹1 recommends turn-of-nut from snug fit to preload as follows: 1/3 turn for bolt grips of 1-4 diameters, 1/2 turn for bolt grips 4-8 diameters, and 2/3 turn for grips of 8-12 diameters. These recommendations are for structural steel fabrication (permanent joints), producing preloads of 100 percent of proof strength and beyond. Machinery fabricators with fatigue loadings and possible joint disassembly have much smaller turns-of-nut. The RB&W recommendation enters the nonlinear plastic deformation zone. The figure shows a cross section of a grade 25 cast-iron pressure vessel, with a torque factor K of 0.09. Use Eq. (8-27) to estimate the torque necessary to establish the desired preload given that preload F; = 14.4 kip, bolt stiffness kb = 5.21 x 106 lbf/in, number of threads N = 11, and material stiffness km = 8.95 × 106 lbf/in. in-11 UNCX 2+ in grade 5 finished hex head bolt in No. 25 CI Determine the torque necessary to establish the desired preload and the turn of the nut in…arrow_forwardRB&W11 recommends turn-of-nut from snug fit to preload as follows: 1/3 turn for bolt grips of 1-4 diameters, 1/2 turn for bolt grips 4-8 diameters, and 2/3 turn for grips of 8-12 diameters.
