This is a nail specifically designed for wood, which will be embedded very firmly in the wood. If the wood is not decayed, it is impossible to pull it out, and even if it is forcibly pulled out, it will bring out nearby wood. One more thing to note is that the wood screws must be screwed in with a screwdriver. Do not knock in with a hammer, it will damage the surrounding wood.
The advantage of wood screws is that the consolidation ability is stronger than nailing, and it can be removed and replaced, which does not hurt the wood surface and is more convenient to use.
