Note:
The torque values must be reduced when installing the fasteners into
threaded aluminum or brass. The specified torque value should be determined
based on the aluminum or base material strength, fastener size, length of thread
engagement, etc.
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. The thin height nuts include
jam nuts.
Note:
Reduce the 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 a thread sealant, such as Loctite.
