Page 48: Sequence Tightening
Sequence Tightening On some assemblies, it is advisable to use a crisscross pattern. Always avoid starting in one spot and tightening one after another in a row. Remember that the object is to tighten the parts in such a manner that even stress is set up throughout, at the same time allowing the parts to be drawn together so that their mating surfaces will contact.
