Nonferrous Metals DIN7969-2017 Slotted countersunk head screws for bolt connection of steel structur
Product details
Slotted countersunk head screws for bolt connection of steel structures play a vital role as key connecting elements in the construction of complex frames in modern architecture and engineering.
Functional characteristics
- Slotted design: The straight-line notch in the top center allows the screwdriver to be inserted and the torque to be applied for fast and accurate tightening.
- Countersunk construction: The contouring of the head is conical and sunken, allowing it to be flush or even slightly dented with the surface of the component after installation, creating a smooth and seamless appearance and reducing potential risks from external protruding, such as wearing clothing or scratching people.
- High-strength material: usually forged from high-quality carbon steel or alloy steel, strengthened by heat treatment to ensure that the screw has sufficient tensile strength and fatigue resistance, to adapt to heavy loads and harsh environments for long-term service needs.
Application
- High-rise building frame: In the steel structure frame of skyscrapers, slotted countersunk screws are used to connect beams, columns and trusses to ensure the stability and safety of the building structure.
- Bridge construction: Whether it is a bridge across a river or an urban overpass, these screws are used to strengthen piers, bridge panels and their attached structures to withstand vehicle loads and the natural environment.
- Factories and warehouses: In the construction of industrial plants and storage facilities, screws are used to secure prefabricated steel wall, roof and floor systems to speed up construction while ensuring structural rigidity.
- Power and energy industry: Power plants, transmission towers and wind turbine towers and other facilities rely heavily on slotted countersunk screws to complete the assembly of heavy steel structures to resist extreme weather effects.
