All,

 

I would like to hear some comments on the validity of torquing
relatively small "self locking" type nuts used for electronic assembly.
Some think that self locking type nuts should only be hand-tightened due
to the measurable run down torque involved and other think that even
these types of fasteners should be torqued.

 

The self-locking feature on deformed type nuts for example presents a
measurable run down torque which should be added to the specified
fastener torque value to obtain I would think the correct adjusted
fastener torque value required.  Comments / experience?   thanks

 

Best Regards,

-Joe
