Tightening torque calculation for screw.xls
KNOWN: A known static tensile load is applied to two metric (ISO) screws.
FIND: Select appropriate screws and specify a tightening torque.
ASSUMPTIONS: 1) A relatively inexpensive class 5.8 steel is chosen for the screw material.
2) The load of 9kN is shared equally by each screw.
3) No bending of the machine screws (bolts) takes place; that is, the bolt load is axial tension.
