Product Overview
This Flattened Eyelet Self-Drilling Tapping Screw is a high-efficiency fastener specially designed for construction, renovation, and equipment mounting applications. Featuring an integrally formed structure and blue anti-corrosion paint coating, it combines high strength, easy installation, and multi-functional hanging capabilities. It is widely used for quick fastening and lifting point connections in metal sheets, light steel keels, roof components, and more.
Key Features
Unique Eyelet Head Design: The flattened eyelet head allows direct threading of cables, hangers, or connectors without additional accessories, enabling "fastening + hanging" in one step.
Self-Drilling Tail Structure: The drill-point tail eliminates the need for pre-drilling, enabling direct penetration into thin steel plates, light steel keels, and other substrates, greatly improving construction efficiency.
Corrosion-Resistant & Wear-Resistant Coating: The blue paint coating provides excellent rust and weather resistance, adapting to complex environments such as humidity and outdoor exposure, and extending service life.
High-Precision Threads: Trapezoidal coarse threads ensure tight engagement, strong holding power, and effective anti-loosening, guaranteeing stable connections.
Customizable Specifications: Dimensions, hole diameters, and surface treatments can be adjusted to meet personalized installation requirements for different projects.

Applications
Building & Renovation: Fixing of light steel keel ceilings, installation of wall hangers, and layout of cable lifting points.
Steel Structure Engineering: Fixing of roof/wall color steel plates and temporary hanging of components.
Equipment Installation: Mounting of electromechanical equipment brackets and connection of pipeline lifting points.
Automotive / Container: Fixing of interior parts and assembly of lightweight components.
Installation Instructions
Align the screw with the installation position and use an electric drill/impact screwdriver with a matching bit.
Start the tool and use the self-drilling function to penetrate the substrate directly without pre-drilling.
Stop applying force once the screw head is tightly attached to the substrate, ensuring full thread engagement.
The eyelet head can be directly threaded with hooks, rings, or cables to complete secondary hanging operations.
Packaging & Storage
Standard Packaging: Packed in cartons/plastic bags with standard quantities per package (customizable per customer request).
Storage Requirements: Store in a dry and ventilated environment, avoid moisture and collision to prevent coating damage.
