Wood screws, also called wood screws, are similar to machine screws, but the threads on the screws are special wood screw threads that can be directly screwed into a wooden component (or part) for fastening a metal (or non-metal) part with a through hole to a wooden component. This connection is also a detachable connection.
This is a kind of nail specially designed for wood. After entering the wood, it will be firmly embedded in it. If the wood is not rotten, it is impossible to pull it out. Even if it is forcibly pulled out, it will bring out the nearby wood. Another thing to note is that wood screws must be screwed in with a screwdriver. Never use a hammer to knock them in, which will damage the surrounding wood.
Wood screws have the advantage of stronger consolidation capacity than nails, and can be removed and replaced without damaging the wood surface. It is more convenient to use.

The oval head screws are usually cadmium chromium plated, and are often used to install loose leaves, hooks and other hardware accessories. The specification is determined by the diameter and length of the rod and the type of the nail head. When purchasing, the unit is the box.
