Answer:
Decrease friction
Explanation:
Carpenters grease screws before driving them into wood. This is done in order to reduce friction. The grease settles down in the hole made due to the driving of the screw. In the long run when the furniture needs some repairing the screws can be taken out easily because of the grease.
