hex head trilobular screw

The DIN 7500 D and UNI 8110 trilobular self-forming screws, characterised by their hexagonal head, are a reliable and versatile solution for fastening on resistant materials. Thanks to their three-lobed shape, these screws are designed to self-form the thread during installation, ensuring a stable and secure connection without the need for pre-drilling. The hexagonal head allows precise and uniform torque application, making them ideal for applications requiring strength and durability. This configuration offers a firm grip with spanners or mechanical tools, reducing the risk of slippage during tightening. DIN 7500 D and UNI 8110 screws are mainly used in the mechanical, automotive and construction industries, where fast and reliable fastening is essential. Available in different sizes, these screws are designed to withstand harsh environmental conditions and ensure excellent durability. The three-lobed design not only facilitates insertion, but also reduces stress on the threaded surfaces, extending the service life of the connections. We offer a wide range of DIN 7500 D and UNI 8110 self-forming screws to meet your specific application needs.
