S-92316A638 3/8"-16 x 3" IFI 111, SAE J429 High-Strength Grade 8 Steel Flanged Hex Head Screws

Key Features & Benefits at a Glance

• Exceptional Load-Bearing Capacity: With a tensile strength of 150,000 PSI, these screws provide reliable performance in high-stress applications, reducing the risk of fastener failure.
• Superior Corrosion Resistance: The black phosphate coating on steel offers enhanced protection against rust and wear, extending the service life in harsh industrial environments.
• Optimized for Quick Assembly: UNC coarse threading and partial threading design allow for faster installation and reduced cross-threading, saving time and labor costs.
• Enhanced Stability with Flange: The integrated flange distributes clamping force evenly, minimizing surface damage and providing a secure, vibration-resistant connection.
• High-Strength Material Integrity: Grade 8 classification and Rockwell C32 hardness ensure durability and resistance to deformation under heavy loads.
• Precision Thread Fit: Class 2A thread fit guarantees consistent engagement and ease of use with standard nuts, improving assembly efficiency.
• Compliance with Industry Standards: Meets SAE J429, RoHS 3, and REACH regulations, ensuring safety, environmental responsibility, and compatibility in global supply chains.

Professional Applications & Engineering Value

Engineered for heavy-duty industrial applications, these Grade 8 hex head screws address common challenges like vibration loosening and corrosion in machinery, construction, and automotive assemblies. The black phosphate steel construction combats environmental exposure, while the UNC coarse thread and partial threading enhance grip in tough materials, reducing installation time. The flange design eliminates the need for separate washers, providing a wider bearing surface that prevents sinking into soft substrates. Ideal for structural frameworks and equipment requiring high tensile strength, these screws ensure long-term reliability and minimize maintenance downtime in demanding conditions.
