General considerations when using all-
metal lock-nuts:
• Do not lubricate all-metal lock-nuts.
•
Bolts and washers can be reused,
but nuts can only be reused once.
If reuse history is unknown, install
new nuts.
• If a bolt must be replaced the nut
installed on it must also be
replaced.
• Fasteners must be torqued from
the nut to achieve correct clamp
load.
NOTE
The previous table with torque values
and the
instructions in this section ap-
ply ONLY to all-metal lock nuts (left im-
age) but do NOT apply to Nylon lock-
nuts (right image).
