Professional Applications & Engineering Value

This 1/2"-13 UNC hex head screw is engineered to address critical challenges in structural and machinery assembly. The 18-8 Stainless Steel material provides excellent resistance to oxidation and chemical exposure, making it suitable for outdoor, marine, and chemical processing applications where corrosion resistance is paramount. The coarse thread and Class 2A thread fit facilitate quick and reliable installation, reducing assembly time while maintaining a secure hold. Its partially threaded shank concentrates the tensile force on the engaged section, preventing joint loosening under dynamic loads. With an external hex drive and substantial 12" length, it is ideal for heavy-duty frameworks, construction projects, and industrial equipment requiring long, high-strength fasteners that endure stress and environmental factors.

Specification Summary & Compliance
