The AIYI 6.3 × 75mm Tek Screws are designed for heavy-duty fastening of roofing sheets, metal panels, and steel structures. Packed in a 100-piece storage jar, these screws are ideal for roofing installers, construction projects, steel framing, fencing, and general metal fixing applications.
Each screw features a self-drilling Tek point, allowing it to drill through metal and fasten in a single step without pre-drilling. This greatly improves installation speed and efficiency when working with roofing sheets, metal cladding, or light steel structures.
The screws use a hex head design, allowing strong tightening with a spanner, socket, or impact driver, providing high torque and secure fastening. Each screw includes a bonded sealing washer, which helps create a tight, weather-resistant seal that reduces the risk of water leaks 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 packed in a clear plastic jar, keeping fasteners organized and easy to transport or store in toolboxes, workshops, or job sites.
