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
oil, graphite, or thread sealant such as Loctite.
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: The nominal torque values listed above for
Grade 5 and 8 fasteners are based on 75% of the mini-
mum proof load specified in SAE J429. The tolerance is
approximately  10% of the nominal torque value. Thin
height nuts include jam nuts.
