A DIN 7420 furniture screw is a specialized fastener widely used in the furniture industry to join various components of furniture. It is distinguished by its high strength, reliability, and aesthetic appearance.
Technical Characteristics of DIN 7420
The DIN 7420 furniture screw is manufactured according to the international standard DIN 7420, which regulates its dimensions, shape, material, and other technical characteristics. This standard ensures high quality and compatibility of the screws with other furniture components.
- Head: Typically cylindrical with a hexagonal socket or Phillips cross-recess.
- Thread: Triangular, metric, with a fine pitch, ensuring a secure fastening.
- Length: Varies and is selected based on the thickness of the material to be joined.
- Diameter: Determined by the DIN 7420 standard and depends on the load the screw must withstand.
Strength Class of DIN 7420
The strength class of a DIN 7420 screw determines its ability to withstand loads without deformation or failure. Typically, medium-strength steel is used for furniture screws, ensuring a reliable connection between furniture components.
Fastener Group DIN 7420
DIN 7420 screws belong to the group of fasteners used to join parts made of various materials such as wood, particleboard, MDF, and others. Due to their design, they provide a strong and reliable connection that can withstand significant loads.
Materials for Manufacturing DIN 7420 Furniture Screws
The main material for manufacturing DIN 7420 screws is carbon steel. It provides high strength, rigidity, and corrosion resistance. To improve decorative properties and corrosion protection, screws can be coated with various types of coatings such as zinc, nickel, or chrome.
