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.
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.
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.
