sturiz 50pcs 410 Stainless Steel Self Tapping Screws Metal Bolts M5.5 Self Drilling Screws for Metal Hex Head Screws with Gasket with Socket for Metal Wood Pvc Plasterboard Number(M5.5x45mm)

• Practical Self Tapping Screws: You will receive 75pcs self tapping screws metal, including 50pcs M5.5 x 45mm and a magnetic sleeve measuring M8x42mm. The ample supply of self drilling screws caters to a wide range of applications, from securing thin sheets to joining thicker materials. The well-balanced combination of different lengths allows users to select the appropriate option flexibly according to specific installation requirements.
• High Quality Materials: This stainless steel self tapping screws set is precision-crafted from premium 410 stainless steel, offering high hardness and strength. Self drilling screws for metal can withstand significant torque and tensile forces without breaking or deforming, and is highly corrosion-resistant. The threads have undergone precision machining to ensure excellent sharpness and stability, enhancing both penetration capability and holding power once tightened.
• Easy to Use: These metal screws come with a hexagonal socket, allowing for immediate use without the need for additional tools. Featuring an external hexagonal head design, they offer a larger contact surface area, making them less prone to slipping during tightening. Self tapping bolts can withstand higher torque, ensuring a more secure and reliable installation. Furthermore, the self-tapping design eliminates the need for pre-drilling; significantly improving installation efficiency.
• Versatile: Tech screws for metal are suitable for securing all types of metal roofing, firmly attaching metal sheets or PVC panels to metal or timber frames. Roof screws are commonly used in the construction of roofs, sheds, garages. Screws for metal are also suitable for the installation and connection of corrugated sheets, cable ducts and sheet metal components. In everyday use, self-tapping screws can also be used to secure furniture, electrical appliances, brackets, doors and windows.
• Waterproof Washer Design: Metal self tapping screws feature a rubber washer design that combines sealing performance with durability. The washers are made from a highly elastic material that distributes pressure evenly during tightening, ensuring a tight seal against the substrate surface to form a reliable waterproof barrier that effectively prevents rainwater, dust and air from entering the joint. Furthermore, the self tapping metal screws possess excellent resilience, ensuring a stable seal.

Precautions for Using self tapping screws for metal 1. Select metal screws self tapping of the appropriate length based on the thickness of the material and the specific application to avoid self-tapping metal screws being too short, which may result in poor fastening, or too long, which may compromise structural stability. 2. When using power tools, ensure the self tappers screws for metal is as perpendicular to the substrate as possible to prevent it from being driven in at an angle. This ensures even force distribution, improves the strength of the joint and reduces damage to the threads. 3. Control the force applied when tightening to avoid over-tightening, which may cause the self-tapping screws for metal to strip or damage the PVC washer, thereby compromising the seal and waterproofing performance. 4. Before installation, ensure the surface is clean and free from oil or debris to enhance the grip between the self tapping screws for metalwork and the material, thereby improving overall fastening performance and durability. 5. During installation, ensure the PVC washer is fully seated to provide effective waterproof sealing. Additionally, avoid repeatedly removing and re-installing metal self tapping screw in the same position, as this may compromise fastening performance and sealing effectiveness.
