S-92316A714 1/2"-13 x 1 1/4" IFI 111, SAE J429 High-Strength Grade 8 Steel Flanged Hex Head Screws

Key Features & Benefits at a Glance

• Exceptional tensile strength of 150,000 psi ensures reliable performance under extreme loads, preventing fastener failure in critical applications.
• Superior corrosion resistance from the black-phosphate steel coating extends service life in harsh industrial environments.
• High hardness rating (Rockwell C32) provides excellent wear resistance and durability, maintaining thread integrity through repeated use.
• Integrated flange design eliminates the need for separate washers, simplifying installation and providing wider bearing surface.
• Precision Class 2A thread fit with UNC coarse threading enables faster assembly and reduced cross-threading risk.
• Full threading along the entire shaft length offers maximum grip and adjustment flexibility in various material thicknesses.
• External hex drive with standard 3/4" head width allows for high-torque installation using common tools.

Professional Applications & Engineering Value

This Grade 8 hex head screw delivers critical engineering solutions where high tensile strength and corrosion resistance are paramount. The black-phosphate steel construction provides superior protection against rust and chemical exposure in manufacturing facilities, construction sites, and heavy equipment applications. The fully threaded design with UNC coarse threads ensures maximum engagement in both thick and thin materials, while the integrated flange distributes clamping force evenly to prevent surface damage. These heavy-duty hex screws are engineered to maintain structural integrity in high-vibration environments, making them ideal for machinery assembly, structural steel connections, and automotive applications where SAE J429 compliance is required.
