Professional Applications & Engineering Value
This 1/2"-13 UNC fully threaded flat head screw is engineered to address critical challenges in heavy machinery, construction, and industrial assembly. The 18-8 stainless steel material and passivated finish provide long-term corrosion resistance, reducing maintenance in humid or chemical-exposed settings. Its coarse thread spacing and Class 3A thread fit enhance grip in soft materials and resist loosening under vibration, while the flat head with 82° countersink ensures a smooth surface to prevent snagging. With a 10" length and hex drive, it offers deep penetration and high torque application, making it a reliable choice for structural supports, equipment frames, and other high-stress industrial applications where precision and endurance are paramount.
Specification Summary & Compliance
This screw adheres to ASME B18.3 specifications, with Class 3A thread fit for precise tolerance and UNC coarse threads (1/2"-13). It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety. Dimensions include a 0.5" thread diameter, 10" length, and standard flat head profile, all manufactured to consistent industrial standards for reliable performance.
