Reduce torque values listed in the table above by 25%
for lubricated fasteners. Lubricated fasteners are de-
fined as threads coated with a lubricant such as engine
oil or thread sealant such as Loctite.
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 fasten-
er size, the aluminum or base material strength, length
of thread engagement, etc.
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 in-
clude jam nuts.
