Phillips round head self-tapping screws with a drilling tail, as defined by DIN571, are a type of self-tapping screw that features a Phillips drive and a round head. These screws are designed to be driven into materials to create their own threads, eliminating the need for pre-drilled holes.
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-Tapping Capability: These screws can create their own threads in materials like wood, metal, and plastic, providing a secure connection without pre-drilling.
Phillips Drive: The Phillips drive provides a high torque transfer and reduces the risk of the tool slipping during installation, which is particularly useful in power tool applications.
Round Head Design: The round head offers a large bearing surface, which helps prevent the material from sinking or cracking, especially in softer materials.
Corrosion Resistance: Often coated with protective finishes like zinc plating or other treatments, these screws resist rust and corrosion, making them suitable for various environments.
Versatility: Available in various sizes and thread pitches, these screws can be used in a wide range of applications, including construction, metal fabrication, and more.
Scope of Application
Metal Sheet Fastening: Ideal for fastening metal sheets in construction or industrial applications where a strong hold is required.
Construction: Used in construction projects for securing materials like formwork, safety barriers, and drywall tracks to concrete or metal structures.
Automotive and Industrial Applications: Employed in the automotive industry for assembling car interiors and in industrial settings for fastening machinery and equipment.
Renovation and Repair: Effective for renovation and repair work where existing structures need to be reinforced or secured with a strong and reliable fastening solution.
Machinery and Equipment Assembly: Used in the assembly of machinery and equipment where a strong and durable fastening solution is needed.
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.
