S-92316A716 1/2"-13 x 1 1/2" IFI 111, SAE J429 High-Strength Grade 8 Steel Flanged Hex Head Screws

Key Features & Benefits at a Glance

• Exceptional strength for demanding applications with Grade 8 classification and 150,000 psi tensile strength, ensuring reliable performance under high stress.
• Superior corrosion resistance from the black-phosphate steel coating, extending service life in harsh industrial environments.
• Enhanced durability and wear resistance due to Rockwell C32 hardness, reducing the risk of stripping or deformation during installation.
• Secure and precise fit with Class 2A thread fit and UNC coarse threading, facilitating easier assembly and reducing cross-threading risks.
• Increased bearing surface and stability from the integrated flange design, distributing load more effectively and eliminating the need for a separate washer.
• Efficient installation and removal using standard external hex drive and hex head, allowing for high torque application with common tools.
• Compliance with major industry standards including SAE J429, RoHS 3, and REACH, ensuring product safety, environmental responsibility, and consistent quality.

Professional Applications & Engineering Value

Engineered for heavy-duty industrial applications, this Grade 8 hex head screw delivers critical performance where failure is not an option. The black-phosphate steel construction provides a robust barrier against rust and corrosion, making it ideal for outdoor machinery, construction equipment, and automotive assemblies exposed to moisture and chemicals. Its UNC coarse thread and Class 2A fit ensure quick, secure fastening in materials like steel and cast iron, reducing assembly time and improving joint integrity. The flanged design increases clamping force and resists loosening under vibration, a common issue in dynamic environments. Fully threaded for maximum grip length, it offers versatile use in structural connections, offering engineers a reliable, SAE J429 compliant solution that meets rigorous mechanical and regulatory demands.
