The AIYI 5.5 x 75mm Self-Drilling Tek Screw Set is designed for strong and reliable fastening in roofing, sheet metal installation, and structural metal work. This pack includes 100 screws, making it suitable for professional contractors, installers, workshops, and DIY projects.
Each screw features a self-drilling tek tip, allowing it to drill and fasten in a single step without the need for pre-drilling. This helps speed up installation when working with roofing sheets, sheet metal panels, light steel frames, and metal structures.
The screws use a hex head design, allowing secure tightening with a socket, spanner, or power drill. Each screw also includes a sealing washer, which helps create a tight seal and helps reduce water penetration in roofing and outdoor installations.
Manufactured from durable coated steel, these screws provide strong holding power and corrosion resistance, ensuring reliable performance in both indoor and outdoor environments.
The screws are packed in a convenient plastic storage jar, helping keep them organized and easy to store in toolboxes or workshops.
