Professional Applications & Engineering Value

This 1/2"-13 UNC hex head screw is engineered to solve critical challenges in industrial fastening. The 18-8 stainless steel provides excellent resistance to oxidation and corrosion, making it ideal for outdoor, marine, or chemical-exposed settings. Its coarse thread spacing and fully threaded design allow for quicker installation and superior grip in soft materials or where vibration loosening is a concern. The external hex drive and substantial head width enable high torque application, reducing the risk of stripping and ensuring a secure, reliable connection in structural assemblies, machinery, and heavy equipment. By combining high tensile strength with compliance to ASME B18.2.1, this screw delivers consistent performance and safety in critical B2B applications.

Specification Summary & Compliance
