NOTE: Torque values may have to be reduced when
installing fasteners into threaded aluminum or brass.
The specific torque value should be determined based
on the fastener size, the aluminum or base material
strength, length of thread engagement, etc.
NOTE: Reduce torque values listed in the table above
by 25% for lubricated fasteners. Lubricated fasteners
are defined as threads coated with a lubricant such as
engine oil or thread sealant such as Loctite

NOTE: The nominal torque values listed above for
Grade 5 and 8 fasteners are based on 75% of the
minimum proof load specified in SAE J429. The
tolerance is approximately ± 10% of the nominal torque
value. Thin height nuts include jam nuts.
