Features
1. Head shape: The head is flange-shaped, typically round or hexagonal, with a bigger diameter than the screw section. This design allows the flange head to have a greater contact surface when the screw is inserted, distributing pressure and improving connection stability.
2. Drill tail design: The screw's tail features a drill-like sharp section that can drill holes without pre-drilling, increasing installation efficiency.
3. Diverse materials: Typically made of carbon steel, stainless steel, or alloy steel, with varying strengths and corrosion resistance, making them appropriate for a wide range of applications.
4. Extensive size options: Different diameters, lengths, and thread standards are available to fulfill various fixing requirements.
Installation method
1. Prepare tools: To install flange head drilling screws, you'll need electric or manual screwdrivers.
2. Choose the correct screw: Choose a flange head self-drilling screw with the proper length and diameter for the material and thickness of the object to be fixed.
3. location the screw: Align the screw's tip with the location to be fastened, and then carefully press the screw into the material's surface.
4. Rotate the screw: With an electric or manual screwdriver, rotate the screw and progressively drill into the material. Keep the screwdriver vertical while turning the screw to ensure that the screw drills easily into the material without damaging the surface.
5. Tighten the screw: Once the screw has been fully drilled into the material, continue to rotate it until the head is flush with the material's surface, or slightly concave.
Precautions
1. Select the proper screw: When selecting a flange head drilling screw, ensure that the screw has the correct length and diameter for the thickness of the material and object to be fixed.
2. Use the proper tool: To install flange head drilling screws, you'll need either an electric or a manual screwdriver.
3. Pay attention to the installation angle: When installing a flange head drilling screw, maintain the screwdriver vertical to guarantee that the screw drills into the material smoothly and without damaging the surface.
4. Avoid over-tightening: When tightening a flange head drilling screw, avoid over-tightening to prevent material or screw damage.
5. Check the installation quality: After installing the flange head drilling screw, inspect the screw to confirm that it has been thoroughly drilled into the material and that the head is flat with the surface or slightly recessed.
