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.
