The AIYI 5.5 x 25mm Self-Drilling Tek Screw Set is designed for fast, secure fastening in roofing, sheet metal, and general construction applications. This pack includes 200 screws, making it ideal for professional contractors, workshops, and DIY 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 makes installation quicker and more efficient when working with sheet metal, light steel, roofing panels, and other metal surfaces.
The screws are fitted with a hex head for strong grip with a spanner or socket, ensuring stable and reliable tightening. Each screw also includes a sealing washer, which helps provide a secure fit and helps reduce water penetration in roofing applications.
Manufactured from durable coated steel, these screws offer strength, corrosion resistance, and long-lasting performance in indoor and outdoor environments.
The screws come stored in a convenient plastic jar, keeping them organized and easy to store in a toolbox or workshop.
