We used to cut a little bit the collar when applying a very high torque and it didn´t break.
I think that happens because of bad quality controls of the manufacturer of the rivets.

Maybe working with aluminium is not a problem, but as you may know when working with composites you can break the matrix because of a very high pressure load. I´m talking about defective rivets, not about forgetting the maintenance manual and applying a more comfortable torque than required.

About the second question no, not any fastener manual allow to cut hilocks. Anyway I was just kidding. We didn´t cut any hilock.
Anyway the problem is not a joke. You can break the matrix when applying a higher load than the specification of the rivet.
Sorry. I´m a very bad joker and don´t make any fun.

Either way, that would overcome the design flaw in the fastener (ha,ha)(what....no sense of humor?)
I hope someone from Boeing reads these threads, but then again, would they really care?
RE: 787 Hi-Lok installation
We changed to suitable alternate collars with aboslutely no supplier fastener support from the fastener manufacturer or the tool manufacturers....
