INCH/METRIC
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
®
.
INCH/METRIC
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.
INCH/METRIC
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.
METRIC NOTE:
The nominal torque values
listed above are based on 75% of the
minimum proof load specified in SAE J1199.
The tolerance is approximately ± 10% of the
nominal torque value. Thin height nuts include
jam nuts.
