What is a wooden screw?
The wooden screw is used to connect two pieces of wood together. Made of steel, a wooden screw usually has a head that is designed for use with a conventional screwdriver or phillips-head. A simple way of identifying the wooden screw from the metal screw is to look at the screw stop. The wooden screw will have an empty stem under the head and above the thorough area, while the metal screw will usually have fine threads running from the screw point to the head without an empty or smooth area at all. Materials used to make a wooden screw can be steel, brass or aluminum-galvanized steel or adhesive steel are other options. The screw is usually not used to drill your own hole; However, some special type screws are intended. When attempting to force the wooden screw to the position without the pilot hole, the wood will usually burst, and the bolt will usually not hold, as well as the screw inserted into the pilot opening. By using the pilot opening, the fibers in the screw are able to bite without being hinderedKy in the hole.
One type of screw, which performs flawlessly without a pilot opening, is the bolt of the plasterboard. Many times the drywall screw is wrong with a wooden screw, even if they are not the same. The drywall screw is a very rough screw screw that is designed to be inserted into the wood without a pilot opening. This type of screw is not designed for structural force and is not made to secure two pieces of wood together. The plasterboard screw is more of a clamp in that it fastens the cover to the wooden wall. By having fibers running along the entire length of the screw, it cannot tighten two pieces of wood together.
The empty stem of the wooden screw allows the screw to rotate freely inside the ometrmost piece of wood and draw the inner piece firmly against it by grasping the wood under the thread and pull. Fully threaded bolt of plasterboard has threads that run inside an outer piece of wood and do not allow to make a scrollUB turned freely while the end threads clamp and pull out the wood. This results in a screw that is very tight - but the wood can remain apart.
