The AIYI 5.5 x 30mm Self-Drilling Tek Screw Set is designed for strong and reliable fastening in roofing, sheet metal, and construction applications. This pack includes 150 screws, making it suitable for contractors, workshops, and DIY installation projects.
Each screw features a self-drilling 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 sheet metal, light steel frames, roofing sheets, and metal panels.
The screws are equipped with a hex head, providing a secure grip for tightening with a spanner, socket, or drill bit. Each screw also includes a sealing washer, which helps improve sealing performance and reduce water penetration in roofing installations.
Manufactured from durable coated steel, these screws offer good strength and corrosion resistance for both indoor and outdoor applications.
The screws are packed in a reusable plastic jar, keeping them organized and easy to store in a toolbox or workshop.
