Professional Applications & Engineering Value
This 6061 aluminum rounded head screw is engineered to address common industrial challenges, such as weight reduction and corrosion in machinery, electronics, and automotive assemblies. The coarse 8-32 UNC thread and Class 2A fit provide rapid installation with minimal risk of stripping, while the flanged button head distributes clamping force evenly, reducing stress concentrations. Made from high-strength aluminum with 40,000 psi tensile strength, it withstands dynamic loads without compromising on lightweight design. Ideal for applications requiring RoHS and REACH compliance, this screw ensures durability and regulatory adherence in sensitive environments.
Specification Summary & Compliance
This screw adheres to UNC coarse thread standards with a Class 2A thread fit for consistent precision. It meets RoHS 3 (2015/863/EU) with exemption 6(b)-II and REACH (EC 1907/2006) compliance, ensuring it is free from hazardous substances. Manufacturing follows strict dimensional tolerances for head diameter, length, and thread specifications, supporting reliable performance in industrial fastening applications.
