Professional Applications & Engineering Value
These 651 Silicon Bronze hex head screws are engineered to solve critical challenges in corrosive environments where standard steel fasteners fail. The silicon bronze material provides inherent resistance to saltwater, chemicals, and atmospheric corrosion, making them ideal for marine applications, coastal structures, and chemical processing equipment. The UNC coarse thread pattern ensures rapid installation and reliable performance in soft materials or where vibration resistance is crucial. With 70,000 psi tensile strength and Rockwell B70 hardness, these fully threaded screws maintain structural integrity under heavy loads while the external hex drive enables high-torque installation without stripping. This combination of material properties and Class 2A thread precision delivers long-term reliability in demanding industrial settings.
Specification Summary & Compliance
This 3/8"-16 UNC hex head screw features Class 2A thread fit for consistent dimensional accuracy and proper mating. Manufactured to ASME B18.2.1 specifications for standard hex head dimensions and thread form. The product is fully compliant with RoHS 3 (2015/863/EU) restrictions on hazardous substances and REACH (EC 1907/2006) regulations for chemical safety. These compliance certifications ensure the fastener meets international environmental and safety standards for industrial applications.
