hex head trilobular screw with flange

The UNI 8111 hexagon head trilobal self-forming screws with flange are an innovative solution for direct fastening on metal and plastic materials, without the need to prethread the hole. Thanks to their three-lobed design, these screws deform the hole material to create a strong and precise thread, guaranteeing an exceptional seal. The hexagonal head with integrated flange offers increased support and even load distribution, improving stability and reducing the risk of loosening. This design is ideal for applications where mechanical strength and ease of installation are priorities. Usable with standard tools, such as hexagonal spanners, the UNI 8111 screws simplify work even in difficult environments. Made from high-quality materials, UNI 8111 screws offer superior tensile, torque and corrosion resistance. The integrated flange eliminates the need for additional washers, ensuring faster and more convenient fastening. These trilobular self-forming screws are available in a wide range of sizes and materials, making them suitable for many industries, including mechanical, automotive and electronics. Their ability to create a durable thread in soft or brittle materials makes them indispensable for robust and reliable assemblies. Choose UNI 8111 hexagon head trilobular self-forming screws to ensure professional and durable fastening.
