Key Features & Benefits at a Glance
- Exceptional load-bearing capability with Grade 8 classification and 150,000 psi tensile strength for demanding industrial applications
- Superior corrosion resistance provided by black-phosphate steel coating, extending service life in harsh environments
- Enhanced installation efficiency through UNC coarse threading and Class 2A thread fit for faster assembly with reduced cross-threading risk
- Increased stability and distribution from the integrated flange design, eliminating the need for separate washers
- Reliable torque transmission via the external hex drive and substantial 1 1/8" head width for secure fastening
- Full-thread engagement along the 1 3/4" length ensures maximum grip strength across the entire fastener
- Regulatory compliance assurance meeting SAE J429/IFI 111 standards and environmental directives (RoHS 3, REACH)
Professional Applications & Engineering Value
Engineered for heavy-duty industrial applications, this Grade 8 hex head screw addresses critical challenges in machinery assembly, structural frameworks, and equipment manufacturing. The black-phosphate steel construction provides essential corrosion protection where lubricants or coatings might degrade, while the UNC coarse threading maintains reliability in high-vibration environments where fine threads might loosen. The integrated flange distributes clamping force effectively across wider surfaces, preventing material deformation in soft substrates. With 150,000 psi tensile strength and Rockwell C32 hardness, this fastener withstands extreme mechanical stresses in construction, automotive, and heavy equipment sectors where failure is not an option.
Specification Summary & Compliance
This 3/4"-10 hex head screw features Class 2A thread fit tolerance for consistent engagement and UNC coarse threading per standardized specifications. Manufacturing complies with IFI 111/SAE J429 standards for dimensional accuracy and mechanical properties. The product is fully RoHS 3 (2015/863/EU) compliant and REACH (EC 1907/2006) compliant, meeting current environmental regulations for industrial components.
