    Two things, perhaps dont REUSE a nyloc, and dont use them on the diff on the inboard flange to disc arrangement, on IRS, they may come lose. WHY, coz get mighty hot and melts the nyloc. Special nuts you need are Phileadas nuts!
    According to Jaguar.

    And just to get in before Myles repeats his sage words from the second or third reply, this is not how any kind of 'lock' nut works - the purpose of which is to stop the nut coming totally off (a fail safe) AFTER it's already become loose - it does not in any way stop it coming loose in the first place (which is done by the applied/specified tightening torque)

    Thanks Russ, my words have been described as many things other than sage...

    I suppose the only thing that comes close to truly locking a fastener would be the high strength version of Loctite : something that can raise the friction A LOT?

    Very interesting video which clearly shows that nylocks do actually help prevent loosening.

    Fixed that for you.

    'Loose' being any level of torque less than the designed value.

    That was very interesting and surprising I thought the various locking systems would perform better especially the nylock nut.

    If it concerns you ( which it shouldent) just grease the shank of the bolts and leave the threads dry. thats the requirement for a lot of aircraft bolts. but whatever you choose to do will be fine.

    That video was impressive in respect of the Nord Locks. Has anyone had any experience of using them?

    We use Nordlock at work on some of the transmissions we do. Great bit of kit and have never come loose.

    Good experience with them myself as well. If you want to undo them, you feel clearly at first some movement of the locked nut (or bolt) but inmidiately the momentum increases to a certain level and then quite suddenly breaks away. For this to work both washers need to dig their teeth into both surfaces. I wonder if they would be able to do so on hardened bolts, f.e. 12.9 steel..?
