Experienced wood workers use steel wood screws of the same size to set the screws thread pattern in a drilled hole of the proper size. The steel is then backed out and the brass ones run in, one time , no chance of breaking the screw.Exercise caution when using small brass screws. Sometimes they can twist off in the wood before they are driven home. If you do use brass, rub candle wax onto the thread. That will lube the screw and ease the installment of the screw. You might have to back the screw out once or twice to rub more wax on. It can save a lot of trouble.
