I would also add some threadlock ?
For the love of god you don't need to do this! Just use the locking tab washer properly, torque up and it'll be fine. I've had so many difficulties undoing front sprockets because people slather them in threadlock and crank them to within an inch of the threads maximum torque-ability!
Is threadlock rearly that good then
4. Apply Loctite® 620 to the threads and install the
new lock washer and retaining nut from the Drive Sprocket Kit. Tighten the drive sprocket retaining
nut to 90Nm (9.0m-kg, 65 ft-lb).
