ISO 15481 Semi-circular head screw with drill bit

    ISO 15481 is a fastener consisting of a semicircular head with a flange, a threaded rod with a full length thread, and a drill. The product is most often used for fastening sheet metal elements to soft materials. With the total thickness of the materials to be fastened up to 4 mm, the design of the hardware allows it to be used without a pre-prepared hole.

Fastening group ISO 15481

     The ISO 15481 self-tapping screw belongs to the stainless steel fastener group.

Materials used to manufacture ISO 15481

     ISO 15481 is available in the following materials:

• Steel, which can be optionally coated with zinc
• Stainless steel (A2, A4) does not need to be coated

Areas of application of ISO 15481

     ISO 15481 Hexagonal head screw with drill bit - this screw is used to connect several structural elements to metal profiles and sheets. They do not require preliminary drilling of holes. Stainless hexagonal head screws for metal with an L-shaped head have a straight slot. If this fastener is equipped with a rubber gasket, it can be used as a roofing fastener. Since the gasket will protect the connection from the effects of adverse weather conditions, it will ensure tightness, reliability and durability of the structure. It is used in various industrial sectors, in construction, repair and installation processes, in mechanical engineering, during the assembly of metal structures, various installations, equipment, roofing, etc.

     In addition, the scope of application directly depends on the material of manufacture and coating of the product:

• Galvanized steel is a good protection against corrosion if the fastener is to be used in an aggressive environment.
• Stainless steel allows the fasteners to be used at significant temperature drops and in aggressive and humid environments.
