Screw clamping force formula
WebbThe "M" designation for metric screws indicates the nominal outer diameter of the screw, in millimeters (e.g., an M6 screw has a nominal outer diameter of 6 millimeters). Where major diameter is: This nominal value allows us to calculate based on the ISO 965: "Metric (ISO) Screw Coarse series (M)", the pitch(P),d2 and d0(that is d3 in the image) values of the … Webb6 apr. 2016 · T = Torque (in-lb) K = Constant to account for friction (0.15 - 0.2 for these units) D = Bolt diameter (inches) P = Clamping Force (lb) I applied this to my problem T = 0.6 N-m = 5.3 in-lb D = 3 mm = 0.12 in K = 0.2 This gives P = T K D = 220 lb = 100 kg. So, I …
