A DIN 7973 self-tapping screw is a versatile fastening element used to join various materials without the need for pre-drilling. Its design ensures a secure and strong connection. Unlike screws with a countersunk head, the DIN 7973 screw has a slightly countersunk head that protrudes slightly above the material surface after screwing.
Technical Characteristics of DIN 7973
- Head: Slightly countersunk, ensuring a secure connection with the material and allowing the screw to be used in places where a low head height is required.
- Slot: Straight, designed for use with flat-head screwdrivers.
- Thread: Metric, ensuring secure screwing into various materials.
- Point: Pointed, facilitating initial screwing.
Dimensions of DIN 7973 Screws with a Slightly Countersunk Head and Straight Slot
The dimensions of DIN 7973 screws are determined by the thread diameter and length. The range of sizes is quite wide, allowing you to choose the optimal option for each specific case. The DIN 7973 standard details the permissible diameters and lengths for different strength classes.
Strength Class DIN 7973
The strength class of DIN 7973 screws is determined by its ability to withstand loads. The DIN 7973 standard defines several strength classes, allowing you to select the screw according to the requirements of a specific application. Most commonly used are screws with a strength class of 4.8 and 8.8, which ensure a high reliability of the connection.
Scope of Application of DIN 7973 Screws with a Slightly Countersunk Head and Straight Slot
DIN 7973 screws are widely used in various industries:
- Construction: for fastening drywall, plywood, wooden elements, and for connecting metal structures.
- Furniture industry: for joining furniture parts, especially where a low head height is required.
- Automotive industry: for fastening upholstery, interior parts.
- Metal structures: for joining thin metal sheets.
Advantages of using DIN 7973 screws:
- Reliability: Ensures a strong connection of various materials.
- Versatility: Can be used for both indoor and outdoor work.
- Economy: Relatively low cost.
- Connection strength: The slightly countersunk head provides additional connection strength.
The use of DIN 7973 screws allows you to quickly and efficiently perform various installation work, ensuring the reliability and durability of structures.
