When doing so, ensure that the carrying handles are screwed into the threaded holes so that they are perfectly straight. If the carrying handles are not screwed in straight, this can make it more difficult or even impossible to unscrew them later on and can damage the threaded holes to the extent that carrying handles can no longer be screwed into them.
