Niton brand hexagonal drill screws, especially those models with plastic heads and dovetail slots, are fasteners designed for high-strength connections. These screws are characterized by the fact that they are self-drilling and self-tapping, meaning that they can drill and tap their own holes in the material to be secured, greatly improving construction efficiency.
Carbon Steel: Typically used for general applications.
Stainless Steel: For environments where corrosion resistance is required.
Alloy Steels: Used in applications requiring high strength or high temperature resistance.
Advantage:
Self-drilling and self-tapping: The drill-tail design allows screws to be drilled and threaded directly into the material without the need for pre-drilling or tapping, simplifying construction steps. Hexagonal head design: Provides a wide bearing surface that makes tightening and loosening operations easier and can withstand higher torque. Plastic Head: The plastic head design provides additional protection against damage to the material surface, as well as some water and moisture resistance. Dovetail Groove: This groove design provides better drive performance and reduces the possibility of slippage during tightening. Corrosion Resistance: Usually galvanized or other surface treatments are used to enhance the corrosion resistance of the screws for outdoor or wet environments.
Scope of Application
Steel structure building: for fixing color steel tiles, metal roofs and walls, and other steel structure connections. Metal plate connection: for the connection and fixing of various metal plates, such as steel plates, aluminum plates, etc. Equipment installation: for fixing machine parts or structural components during the installation of machinery and equipment. Outdoor signs and billboards: used for fixing outdoor signs, billboards and other structures without worrying about the screws being corroded or damaged by environmental factors. Repair and Maintenance: Used to replace or reinforce structural components during repair and maintenance work, providing fast and reliable connections.
Without auxiliary processing, and can be drilled, tapped and locked directly on the setting materials and foundation material, greatly saving the construction time. They have high pulling force and maintenance force, and will not loosen for a long time after combination.
When to use tapping screws, when to use tapping and drilling screws?1. Tapping screws are used for the connection between thin metal plate (steel plate, saw plate, etc.). When connecting, first make the threaded bottom hole of the connecting piece, and then screw the tapping screw into the threaded bottom hole of the connecting piece. Due to the high hardness of the threaded surface of the tapping screw (≥45HRC), internal threads can be tapped into the threaded bottom hole of the connecting piece to form a connection.2. Self-drilling and tapping screw can be directly in the setting material, basic material drilling, tapping, locking one-time fast completion, can quickly automatic drilling and directly screw fixed; The construction efficiency of self-drilling and tapping screws is very high; It saves the construction time to the maximum extent, improves the construction efficiency and improves the economic benefits of the boss. Self-drilling and tapping screw riveted connector has strong binding force, high preload force and high stability of the connector.
