Self-tapping screws for meshes and the Shell technique

This innovative system is designed to significantly reduce the time required for mesh fixation, offering a considerable advantage in terms of efficiency and practicality. Thanks to its advanced design, pre-drilling of the socket is not required in most cases, thereby simplifying the installation process.

This result is achieved through the special tip design, which allows for quick and precise penetration, and the extremely aggressive threading, which ensures a firm and secure grip.

The system offers a wide range of screws to meet various application needs. The screws are available in different head diameters, ranging from 3.00 mm to 4.5 mm, and in various lengths, from 3 mm to 15 mm. Additionally, two types of drive connections are available—square and cross—to ensure maximum versatility and adaptability to different fixation scenarios.
