In general, oils should only be used for the long axles and greases for the screws. Adjusting screws should not be able to turn themselves, but should also be protected against rust. Therefore, they are burnished with oil. You warm them up and then dip them in oil. Wood screws are mostly made of nickel silver or silver-plated and therefore cannot rust.
