- Full threading along 1" length maximizes grip strength and distribution across the entire fastener
- Rockwell B80 hardness maintains thread integrity and resistance to deformation during repeated use
Professional Applications & Engineering Value
This 1/2"-13 UNC hex head screw delivers exceptional engineering value in demanding applications where corrosion resistance and structural integrity are paramount. The 18-8 Stainless Steel composition provides excellent protection against rust and chemical exposure, making it ideal for marine equipment, food processing machinery, and outdoor structural assemblies. The flanged design distributes clamping force over a wider surface area (1 5/64" flange diameter), preventing surface damage and maintaining joint integrity in vibration-prone environments. With its coarse UNC threading and Class 2A fit, this fully threaded screw ensures rapid installation and reliable performance in heavy-duty industrial fastening applications, from machinery frames to structural supports.
Specification Summary & Compliance
This hex head screw features precise 1/2"-13 UNC coarse threads with Class 2A thread fit for consistent engagement and assembly. Manufacturing complies with ASTM F593 specifications (IFI 111) for material quality and performance. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and regulatory adherence for industrial applications worldwide.
