Wooden screws are similar to machine screws, but the thread on the screw is a specialized thread for wooden screws, which can be directly screwed into wooden components (or parts) to securely connect a metal (or non-metal) part with a through hole to a wooden component. This type of connection also belongs to detachable connections.
The common types of wooden screws are iron and copper, and the types vary depending on the nail head, including round head type
Flat head type and oval head type, there are two types of screws on the nail head: slotted screws and cross slot screws. Generally, round head screws are made of soft steel and are blue in color. Flat head screws are polished, and oval head screws are usually cadmium chromium plated. They are commonly used for installing hinges, hooks, and other hardware accessories. The specifications are determined by the diameter, length, and nail head type of the rod.
Wooden screws, there is a section that is a polished rod, and the tooth pattern angle and pitch of the wooden screw are different from those of self tapping.
Self tapping screws have high hardness, wide thread spacing, deep threads, and an unsmooth surface, while wooden screws have the opposite effect. Another difference is more pronounced, as there is no thread in the rear section of wooden screws. Self tapping screws generally require heat treatment, and wood screws are not necessary. The concept of self tapping screws is actually quite general, as they are divided into different types according to their head shape.
The purpose of wooden screws is similar to machine screws, but the thread on the screw is a specialized ribbed wooden screw that can be directly screwed into wooden components (or parts).
note：
The advantage of screws is that they have a stronger bonding ability than nails, and can be removed and replaced, making them less harmful to the wooden surface and more convenient to use.
This is a type of nail specifically designed for wood, which will be firmly embedded in the wood once it enters. If the wood is not rotten, it is impossible to pull it out, even if it is forcibly pulled out, it will bring out nearby wood. Another thing to note is that wooden screws must be screwed in with a screwdriver. Do not use a hammer to drive them in, as it may damage the surrounding wood.
The installation tool for wooden screws is a screwdriver, which is used as its loading and unloading tool. It has two types of shapes that match the groove shape of the wooden screw head: a straight and a cross shape; In addition, there is a special screwdriver installed on the bow drill, suitable for loading and unloading larger wooden screws, which is more convenient and labor-saving to use.
