GENERAL TIGHTENING TORQUE

SPECIFICATIONS

This chart specifies tightening torques for stan-

dard fasteners with a standard ISO thread pitch.

Tightening torque specifications for special com-

ponents or assemblies are provided for each

chapter of this manual. To avoid warpage, tight-

en multi-fastener assemblies in a crisscross pat-

tern and progressive stages until the specified

tightening torque is reached. Unless otherwise

specified, tightening torque specifications re-

quire clean, dry threads. Components should be

at room temperature.
