All,
I am currently looking at replacing fasteners on an automotive product and have been testing a number of alternatives.
My tests seem to show that fasteners with a captive washer perform worse than flanged fasteners with regards to torque retention. Does anybody have any advice or can point me to any external studies with regards to this?
Also with regards to plastic components, what are the best methods of prevention torque loss over time. Because the bolt or stud cannot be stressed, I assume locking fasteners must be used (e.g. Nyloc). Is this the case (in mass production) or are there other alternatives?
Many Thanks,
Rob
