Professional Applications & Engineering Value
These hot-dipped galvanized steel hex head screws are engineered to address critical industrial fastening challenges where corrosion resistance and structural integrity are paramount. The UNC coarse thread configuration ensures rapid installation in steel frameworks, construction equipment, and machinery assemblies, while the partial threading design concentrates strength where needed most. The zinc-rich galvanized coating provides sacrificial protection against rust in outdoor applications, marine environments, and chemical exposure zones. With their 60,000 psi tensile strength and external hex drive, these screws deliver reliable performance in structural connections, heavy equipment manufacturing, and infrastructure projects requiring durable, long-lasting fastening solutions.
Specification Summary & Compliance
Manufactured to precise dimensional standards with Class 2A thread fit and UNC coarse thread specifications. These hex head screws comply with ASME B18.2.1 dimensional requirements and ASTM A307 material specifications for carbon steel bolts. The product meets RoHS 3 (2015/863/EU) compliance for hazardous substance restrictions and REACH (EC 1907/2006) regulations for chemical safety, ensuring environmental responsibility and regulatory adherence for industrial applications.
