General Torque Specifications
(rev. 4/97)
TORQUE SPECIFIED IN FOOT POUNDS -
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
331432/1432RS/1632/1432/1432RS/1632/1632RS 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.
