General Torque Specifications

(rev. 4/97)
This chart provides tightening torques for general purpose applications when special torques are not specified on process or drawing.
Assembly torques apply to plated nuts and capscrews assembled without supplemental lubrication (as received condition). They do not
apply if special graphite moly-disulfide or other extreme pressure lubricants are used. When fasteners are dry (solvent cleaned) add 33%
to as received condition torque. Bolt head identification marks indicate grade and may vary from manufacturer to manufacturer. Thick nuts
must be used on Grade 8 capscrews. Use value in [ ] if using prevailing torque nuts.
