Descriptions of cheese head screw:

   Wood screw is the same as machine screw yet its thread is special thread for wood screw. It can be directly screwed into the wood structure (or parts) to connect the metal material (or non metal material material) component with wood components tightly. This kind of connection belongs to detachable connection.

Characteristics of cheese head screw:

1.Wood screw usually has iron and copper two types with different head styles like round, flat, and elliptical head types. There are I-shaped and cross-shaped two recesses on the head. Round head wood screw is generally made of soft steel and present with blue color. Flat head type is polished and elliptical head type is usually coated with cadmium and chromium.

2.This kind of wood screw can be applied to install loose-leaf, hook and other hardware fittings. Its specifications are determined by the stem diameter, length and head type. Wood screw has stronger consolidation and connection ability than nails and it can be removed and replaced and it won’t do much harm to the surface of the wood and it is convenient to use.

3.Wood screw is specially designed for wood and it will firmly embed into the wood and if the wood is not rotten, it cannot be pulled out. Even being forcibly pulled out, it will drag out the wood nearby. Wood screw should be screwed into the wood with screwdriver and forcibly knocking in will break the surrounded wood structure.

4.Screwdriver is the assembling and unassembling tool of wood screw and it has I-shaped and cross-shaped two kinds because of the two kinds of recessed on the head of the wood screw. There is also a screwdriver that is installed on the arched drill which is suitable for large wood screws because this kind of screwdriver is convenient and effort saving.

Selection and use:

1.Self-tapping screw is suitable for the connecting and fastening of metal material with prebored holes. It can tap inner thread automatically on the metal and complete thread engagement to play the role of fastening. Because the bottom diameter of its thread is large and its buried depth is shallow. Because its thread pitch is small and the wood structure between each two thread is less. Therefore, self-tapping screw is dangerousand unreliable for wood connected elements especially loose wood.

2.Fine thread drywall screw is perfectly suitable for connecting and fastening the metal frames and gypsum board. But it has the same flaws with self-tapping screw. Fine thread drywall screw has large head diameter and bad head burying ability, thus it will not as flat as the surface of the connected elements after installation.

3.Traditional wood screw needs prebored holes on the wood connected elements before installation or the wood will be easy to crack. Traditional wood screw is not processed with thermal treatment and it is easy to be broken by screwing with electric tool yet manual installation will cost much effort.

4.Chipboard screw is a new type of wood screw and it should be installed by electric tools. It has simple thread design and it cannot solve the wood cracking problem. It has no any advantages on screwing speed and screwing torque.
