Question is, why does SS (Nick) tell all about them? I think one who watches those videos is not likely an 'inept' owner and removing them is required for the 'advanced' maintenance procedures being demonstrated.
If SS wants to apply stuff to set screws they should start with blue loc-tite on the way tube retaining screws and tighten them. A bit of history raising its head here!]
If I get your drift, wasn't that in point of fact a 10er that flew apart and started a new chapter in products liability?
