Hexagon Head Wood Screw

The hexagon head wood screw is a common fastener used for wood. The following is the relevant introduction to the hexagon head wood screw:

Structural Features of the Hexagon Head Wood Screw

Head Shape: The head is hexagonal. This shape provides a larger contact surface and better torque transmission ability. Tools such as wrenches can be used to tighten or loosen the screw more conveniently and powerfully. Compared with wood screws with slotted or cross recessed heads, it can withstand greater torque and reduces the possibility of head damage during the tightening process.

Thread Part: Similar to other wood screws, it usually adopts coarse threads with a relatively large thread profile angle and a relatively deep thread depth. This design helps to obtain a good grip in the wood, enabling the screw to be firmly fixed in the wood. For hexagon head wood screws of different specifications, the thread pitch varies according to the diameter and length. Generally, the larger the diameter, the larger the pitch.

Dimensional Specifications of the Hexagon Head Wood Screw

The diameter usually ranges from 3 to 10 millimeters, and common diameters are 3 millimeters, 4 millimeters, 5 millimeters, 6 millimeters, etc.

The length generally ranges from 10 to 150 millimeters, such as 15 millimeters, 25 millimeters, 35 millimeters, 50 millimeters, etc., to meet the connection requirements of woods with different thicknesses. Its specification is usually expressed as "diameter × length". For example, "5×30" indicates a hexagon head wood screw with a diameter of 5 millimeters and a length of 30 millimeters.

Materials of the Hexagon Head Wood Screw

Generally, carbon steel is mostly used as the material, and appropriate heat treatment is carried out to improve the strength and toughness of the screw. To prevent rusting, surface treatment is usually carried out. Common surface treatment methods include galvanizing, nickel plating, etc. These treatments can form a protective film on the surface of the screw, effectively improving its corrosion resistance and extending its service life.

In some special occasions with high requirements for corrosion resistance, hexagon head wood screws made of stainless steel are also used. Stainless steel has good corrosion resistance and oxidation resistance and can maintain good performance in harsh environments such as humidity, acids, and alkalis.

Working Principle of the Hexagon Head Wood Screw

When using a wrench to screw the hexagon head wood screw into the wood, the thread will cut out a corresponding spiral channel in the wood. As the screw is screwed in, the wood fibers are squeezed and deformed and surround the thread, generating frictional force and clamping force, thus tightly connecting the wood together. The larger torque transmission ability provided by the hexagon head enables the screw to be screwed into the wood more easily and can be tightened more firmly, resulting in a more secure connection.

Application Fields of the Hexagon Head Wood Screw

Furniture Manufacturing: In furniture production, it is often used to connect some components that bear relatively large forces, such as the frame connection of large wardrobes, the connection of sofa structural parts, etc. Since it can withstand greater torque and tensile force, it can ensure the structural stability of the furniture and extend the service life of the furniture.

Construction: It is widely used in the construction of wooden structures in the construction field, such as the erection of wooden roof trusses, the fixing of wooden formwork, etc. Hexagon head wood screws can quickly and firmly connect the wood together, improving the construction efficiency and ensuring the strength and stability of the wooden structure.

Wooden Packaging: For some wooden packaging boxes, pallets, etc. that require sturdy packaging, hexagon head wood screws are commonly used connecting fasteners. It can make the connection between the wooden boards tighter, withstand greater pressure and impact force, and protect the items inside the packaging from damage during transportation and storage.

Precautions for Selecting the Hexagon Head Wood Screw

Select the size according to the thickness of the wood and the connection strength requirements: Ensure that the length of the screw is sufficient to penetrate the connected wood component. It is generally recommended that the length of the screw be 20% - 30% longer than the total thickness of the connected wood to ensure that there is enough thread embedded in the wood to provide a firm connection. For connection parts that bear a large tensile force or shear force, screws with a larger diameter should be selected; for some parts with a smaller force, screws with a smaller diameter can be selected to save costs and avoid causing excessive damage to the wood.

Consider environmental factors: If the use environment is relatively humid or prone to contact with water, hexagon head wood screws made of stainless steel or with good anti-corrosion treatment should be preferentially selected to prevent the screws from rusting and corroding, which may affect the reliability of the connection. In a high-temperature environment, the thermal stability of the screw needs to be considered, and appropriate materials and specifications should be selected to ensure that the connection performance is not affected by temperature.
