Fasteners
Company Overview and Heritage
LLS Titanium, established in Brescia, Italy, in 1990, has over three decades of experience specializing in the production of fasteners and mechanical parts from pure titanium, high-strength aluminum (Ergal), and special steels. The company was among the first in Italy to produce hot-stamped and cold-rolled titanium components and pioneered water-cutting techniques in Brescia, becoming the second in Lombardy to adopt this technology. LLS Titanium is recognized for its competence, precision, and reliability in meeting complex technological demands across various industries.
Products and Specialized Offerings
LLS Titanium provides a comprehensive range of metal fasteners, including screws and small parts, available as standard catalog items or custom-designed based on client specifications. Their product portfolio encompasses diverse types such as cheese head screws, pan head bolts, countersunk bolts, hexagon and double hexagon bolts, and nuts, often with specific technical details like internal serrations, various thread types (e.g., MJ thread), and different head recesses. These components are manufactured from materials like titanium alloys (e.g., 3.7164.7) and corrosion-resisting steels (e.g., 1.4944.6), designed for demanding applications with specified tensile strengths up to 1100 MPa and temperature resistances up to 650 °C.
Industry Applications and Advantages
The company's fasteners are utilized in critical sectors including aeronautical, aerospace, nautical, automotive (including racing), medical, and galvanic industries. Titanium, a primary material, offers significant advantages such as exceptional strength, lightweight properties, inoxidability, and resistance to chemical and external agents. Its amagnetic qualities, aesthetic appeal, high strength-to-weight ratio, and electrical conductivity make it suitable for a wide array of high-performance applications where customized, high-quality fasteners are essential.
Manufacturing Excellence and Certifications
LLS Titanium adheres to stringent quality and manufacturing standards, holding UNI EN ISO 9001:2015 and AS / EN 9100:2018 certifications, particularly crucial for the aerospace sector. Their manufacturing processes include controlled head forging to maintain material grain continuity, cold rolling of threads for enhanced resistance and reduced notch sensitivity, and comprehensive testing such as microstructure examinations, tensile tests, double shear tests, tension fatigue tests, hardness tests, and magnetic or dye penetration testing by aerospace-qualified personnel. Fasteners are tracked and controlled at every production stage to ensure reliability for critical applications.
