- Exceptional tensile strength rated at 80,000 psi ensures reliable fastening in heavy-duty applications
- Optimized torque transmission through external hex drive and 1 11/16" head width for secure installation
- Enhanced thread engagement with Class 2A thread fit and coarse UNC threading for vibration resistance
- Partial threading design provides superior clamping force distribution across the 6" length
- Consistent hardness at Rockwell B70 maintains structural integrity under repeated stress
- Regulatory compliance with ASME B18.2.1, RoHS 3, and REACH standards for quality assurance
Professional Applications & Engineering Value
These 1 1/8"-7 UNC hex head screws deliver critical engineering solutions where corrosion resistance and high tensile strength are paramount. The 18-8 stainless steel composition prevents degradation in chemical exposure and outdoor applications, while the coarse thread design ensures rapid assembly and superior vibration resistance in heavy machinery, structural steel connections, and industrial equipment. The partially threaded configuration concentrates clamping force precisely where needed, preventing joint loosening under dynamic loads. With external hex drive compatibility and substantial 1 11/16" head width, these screws accommodate high torque applications without stripping, making them ideal for maintenance, construction, and manufacturing operations requiring dependable, long-term fastening solutions.
Specification Summary & Compliance
Manufactured to precise Class 2A thread fit tolerances with UNC coarse threading (1 1/8"-7) and right-hand thread direction. These hex head screws comply with ASME B18.2.1 manufacturing specifications and demonstrate full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. The 6" length with 2 1/2" minimum thread length ensures consistent performance across industrial applications.
