Machine Design Bolt Selections and Design Dimensions of standard threads (UNF/UNC) Strength specifications (grades) of bolts. Clamping forces The bolt force is ecbbibFkkkFF Where Kb and KC are the bolt and the clamping material stiffness and Fi is the initial bolt tensioning. Calculating Kb and Kc are relatively difficult and exam problems often give you theses stiffnesses or their ratio. Fe 2 The clamping force is ecbcicFkkkFF Recommended initial tension (for reusable bolts) Fi = ( to ) SpAt Where Sp is the proof strength and At is the tensile area of the bolt.
