The AIYI 6.3 x 40mm Tek Screws are designed for secure fastening of roofing sheets, metal panels, and steel structures. Packed in a 100-piece storage jar, these screws are ideal for roofing installers, contractors, construction work, and DIY projects.
Each screw features a self-drilling Tek point, allowing it to drill and fasten in one step without pre-drilling. This makes installation faster and more efficient when working with sheet metal, roofing sheets, and light steel framing.
The screws use a hex head design, allowing them to be easily tightened with a spanner, socket, or impact driver for strong torque and reliable fastening. Each screw also includes a bonded sealing washer, helping create a tight, weather-resistant seal that helps prevent water leakage in roofing applications.
Manufactured from durable zinc-plated steel, these screws provide excellent strength and corrosion resistance, making them suitable for both indoor and outdoor use.
The screws are packaged in a clear plastic jar, keeping fasteners organized and easy to store in toolboxes, workshops, or on job sites.
