Professional Applications & Engineering Value
This 6061 aluminum rounded head flanged screw is engineered to address common industrial fastening challenges, such as component loosening under vibration and uneven load distribution. The wide button head design combined with the integrated flange provides a larger bearing surface, effectively distributing clamping force and minimizing the risk of surface damage in softer materials. With its UNC coarse threads and Class 2A thread fit, it ensures quick assembly and reliable holding power in machinery, electronics enclosures, and structural frameworks. The hex drive allows for high-torque installation without slippage, making it ideal for automated or manual assembly lines where efficiency and durability are critical.
Specification Summary & Compliance
This screw meets Class 2A thread tolerances for consistent fit and performance, adhering to UNC coarse thread standards. It is fully compliant with RoHS 3 (2015/863/EU) under exemption 6(b)-II for lead in aluminum alloys and REACH (EC 1907/2006) regulations, ensuring it meets environmental and safety requirements for industrial use.
