Professional Applications & Engineering Value
This 1/2"-13 UNC hex head screw is engineered to solve critical fastening challenges in demanding industrial settings. The 18-8 Stainless Steel material delivers exceptional corrosion resistance, making it suitable for outdoor, marine, and chemical exposure applications where rust prevention is paramount. Its coarse thread and Class 2A thread fit ensure quick, secure installation in wood, metal, and composite materials, reducing assembly time and minimizing cross-threading risks. The partially threaded design enhances structural integrity by providing a non-threaded section that improves shear resistance and distributes clamping force more effectively. With an external hex drive and substantial 13" length, it is ideal for heavy-duty construction, machinery assembly, and infrastructure projects requiring robust, long-lasting connections.
Specification Summary & Compliance
This screw features a 1/2"-13 UNC coarse thread with Class 2A thread fit for precise dimensional accuracy and reliable performance. It is manufactured in accordance with ASME B18.2.1 specifications, ensuring consistency and interchangeability. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming it is free from hazardous substances and safe for industrial use.
