In all cases, the minimum spacing (or lack thereof) is determined by the clamping tool. Two cases can be considered.

  • Rigid parts under bending without joints

    If continuity of contact is desired, taking into account the above comments and in the most favorable case, the spacing between two successive bolts should be checked:

    δ<3,5 d

    In fact, this condition is, in most cases of assemblies, far too restrictive; in many cases, a slight separation of the parts between two successive bolts will be acceptable. The problem that arises is that of the shape of the parts to ensure that the assembly can withstand the...
