Professional Applications & Engineering Value
Engineered for demanding industrial applications, these Bumax 88 stainless steel hex head screws deliver superior performance where corrosion resistance and structural integrity are paramount. The 1/2"-13 UNC coarse thread configuration ensures rapid installation in heavy machinery, structural steel connections, and marine equipment, while the external hex drive accommodates high-torque applications without stripping. The partially threaded design concentrates clamping force precisely where needed, preventing joint loosening under vibration. With exceptional 110,000 psi tensile strength, these fasteners maintain integrity in high-stress environments including chemical processing, offshore platforms, and power generation infrastructure where reliability cannot be compromised.
Specification Summary & Compliance
This 3" length hex head screw features precise Class 2A thread fit tolerances with 1/2"-13 UNC coarse threading and 3/4" head width for optimal wrench engagement. Manufactured to ASME B18.2.1 specifications, these fasteners are fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring they meet the highest standards for industrial use while maintaining exceptional material properties and dimensional accuracy.
