S-92316A234 7/16"-14 x 2 1/2" 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 in the most demanding heavy-duty applications, reducing the risk of fastener failure.
• Superior corrosion resistance from the black-phosphate steel coating extends service life and maintains integrity in harsh industrial environments.
• High-strength Grade 8 classification and Rockwell C32 hardness provide consistent durability and resistance to wear under high-stress conditions.
• Flanged hex head design offers increased bearing surface for better load distribution and eliminates the need for a separate washer, simplifying installation.
• Coarse UNC threads with Class 2A fit ensure quick, easy assembly and reliable grip in a variety of materials, reducing installation time and errors.
• Partially threaded shank allows for precise clamping force on the joint without thread interference, enhancing joint stability and vibration resistance.
• Compliance with SAE J429, RoHS 3, and REACH standards guarantees product quality, safety, and environmental responsibility for global industrial use.

Professional Applications & Engineering Value

This Grade 8 hex head screw is engineered to address critical challenges in heavy machinery, construction, and automotive assemblies where high tensile strength and corrosion resistance are paramount. The black-phosphate steel construction combats rust and wear, while the coarse UNC thread and Class 2A thread fit facilitate rapid installation in coarse-grained materials, minimizing cross-threading risks. The flanged design distributes load evenly, preventing surface damage and maintaining joint integrity under dynamic loads. Ideal for structural frames, engine components, and industrial equipment, this screw delivers reliable fastener strength and longevity, reducing maintenance downtime and ensuring operational safety in rigorous environments.
