Professional Applications & Engineering Value
Engineered for heavy-duty industrial applications, these Grade 8 hex head screws deliver exceptional performance in construction machinery, agricultural equipment, and structural assemblies. The black-phosphate steel construction provides superior corrosion protection while maintaining Rockwell C32 hardness for wear resistance. The 3/8"-16 UNC coarse thread configuration ensures rapid installation and reliable performance in high-vibration environments, while the flanged design distributes clamping force evenly, preventing surface damage and reducing assembly components. These partially threaded fasteners offer precise control where full threading isn't required, making them ideal for pivot points and adjustable mechanisms in industrial equipment.
Specification Summary & Compliance
This 4" hex head screw features precise Class 2A thread fit with UNC coarse threading (3/8"-16) and 1" minimum thread length. Manufactured to IFI 111 specifications meeting SAE J429 Grade 8 requirements, ensuring consistent mechanical properties including 150,000 psi tensile strength. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations for safe industrial use worldwide.
