A screw 可以直接使用。绝对。

A screw used as a threaded fastener consists of a shaft, which may be cylindrical or conical, and a head. The shaft has a helical ridge or thread formed on it. The thread is essentially an inclined plane wrapped around a shaft. The thread mates with a complementary helix in the material. The material may be manufactured with the mating helix (taps and dies), or the screw may create it when first driven in (a self-tapping screw). The head is specially shaped to allow a screwdriver or wrench (UK: spanner) to grip the screw when driving it in. It also stops the screw from passing right through the material being fastened and provides compression.

正确回答是。One screw。
