Countersunk head self-drilling screws , with ribs and wings

High-performance Phillips flat countersunk head self-drilling screws, meticulously engineered for superior fastening solutions. Featuring ribs and wings, these screws are designed to deliver optimal performance and reliability in various construction applications.

Features: Headform: Countersunk with ribs for a flush finish and enhanced stability. Drive: Cross recess H (Phillips) ensures secure and easy driving. Thread: Fully threaded for maximum grip and holding power. Material: Made from high-quality steel, ensuring durability and strength. Material Execution: Case-hardened for exceptional hardness and resistance to wear. Surface: Zinc plated blue finish provides excellent corrosion resistance and a sleek appearance. Hardness: Achieves 560 HV, guaranteeing robust performance under demanding conditions.
Assembly Instructions Wings: The wings behind the drill head create a clearance hole in the timber, which is larger than the screw thread diameter. Timber: As the wings strike the metal substructure, they shear off, allowing the screw to penetrate the substructure effectively. Metal Substructure: The screw drills its own core hole into the metal substructure and forms a thread, securing the timber to the substructure. The ribs under the head trim the drilled hole, ensuring a clean and precise countersink.
Specifications Diameters: Available in a range of standard diameters to suit various applications. Lengths: Offered in multiple lengths to accommodate different material thicknesses. Surface Coating: Zinc plated blue finish for enhanced corrosion resistance and aesthetic appeal.
Functionality and Benefits Secure Fastening: The fully threaded design ensures a strong and reliable connection between materials. Durability: Case-hardened steel construction provides long-lasting performance and resistance to wear. Corrosion Resistance: Zinc plated blue finish protects against rust and corrosion, extending the lifespan of the screws. Precision: Ribs under the head ensure a clean and professional finish, with the countersunk design providing a flush surface.
Application Scenarios Construction: Ideal for fastening timber to metal substructures in construction projects. Carpentry: Perfect for woodworking applications requiring secure and durable connections. DIY Projects: Suitable for a variety of home improvement projects where high-quality fastening is essential.
