fication for special components or assemblies are included in applicable section of this book. To
avoid warpage, tighten multi-fastener assemblied in a criss-cross fashion, in progressive stages,
until full torque is reached. Unless otherwise specified, torque specifications call for clean, dry
threads. Components should be at room temperature.
