The AIYI 5.5 x 40mm Self-Drilling Tek Screw Set is designed for secure fastening in roofing, sheet metal, and construction applications. This pack includes 200 screws, making it ideal for contractors, workshops, and DIY installation projects.
Each screw features a self-drilling tip, allowing it to drill and fasten in one step without the need for pre-drilling. This helps speed up installation when working with sheet metal, roofing sheets, light steel frames, and metal panels.
The screws are equipped with a hex head, providing a strong grip for tightening with a spanner, socket, or power drill. Each screw also includes a sealing washer, which helps create a tight seal and helps reduce water penetration in roofing applications.
Manufactured from durable coated steel, these screws provide strength, corrosion resistance, and reliable performance for both indoor and outdoor use.
The screws come packaged in a convenient storage jar, helping keep them organized and easy to store in toolboxes or workshops.
