Professional Applications & Engineering Value
Engineered for demanding industrial applications, these Grade 5 Titanium rounded head hex screws address critical challenges in aerospace, medical equipment, and high-performance machinery. The titanium material delivers exceptional corrosion resistance and a high strength-to-weight ratio, reducing component weight while maintaining structural integrity under dynamic loads. With fine UNF threading (10-32) and Class 2A thread fit, these screws provide superior vibration resistance and precise alignment in tight-tolerance assemblies. The hex drive style ensures reliable torque transmission during installation, minimizing strip-out risks in repetitive maintenance cycles. Ideal for applications requiring RoHS 3 and REACH compliance, these fasteners offer long-term reliability in corrosive or regulated environments.
Specification Summary & Compliance
This 10-32 UNF screw features a 1/2" length with fully threaded fine UNF threading and Class 2A thread fit for precise dimensional accuracy. Manufactured to ASME B18.3 specifications, it meets Rockwell C36 hardness and 130,000 psi tensile strength requirements. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental and safety standards for industrial use.
