I see lots of photos posted where people show keys that are supposedly improperly staked.

The military standard is that the stakes should not distort the side surfaces, and they should result in a removal torque no less than 55 and no more than 100 inch-lbs.

I would bet that many of the "improperly staked" keys are in spec of 55-100 inch-lb removal torque, and many of the home stake-jobs are over 100 inch-lbs removal, and hence out of spec.

So before you re-stake your carrier, perhaps check to see if you can remove the screw with less than 55 inch-lbs of torque. If you cannot, then it is in spec.
