S-92323A567 7/16"-14 x 1" IFI 111, SAE J429 Medium-Strength Grade 5 Steel Serrated-Flange Hex Head Screws

Key Features & Benefits at a Glance

• Exceptional Load-Bearing Capacity: With a tensile strength of 110,000 psi, this screw reliably handles high-stress applications, reducing the risk of fastener failure in demanding environments.
• Superior Corrosion Resistance: The zinc-plated steel construction provides a durable protective layer, extending service life and maintaining integrity in humid or outdoor settings.
• Optimized for Quick Installation: The coarse UNC threading and external hex drive allow for rapid assembly with standard tools, saving valuable labor time on the production line.
• Enhanced Vibration Resistance: Integrated serrations under the flange create a secure locking mechanism, preventing loosening under dynamic loads and minimizing maintenance needs.
• Precision Thread Fit: Class 2A thread tolerance ensures consistent, reliable engagement with mating components, reducing cross-threading and improving assembly quality.
• Versatile Flange Design: The integrated flange distributes clamping force over a wider area, providing increased stability without requiring separate washers.
• Certified Material Hardness: Rockwell C22 hardness rating guarantees consistent performance under torque, preventing stripping and ensuring reusable fastening integrity.

Professional Applications & Engineering Value

Engineered for heavy-duty industrial applications, this Grade 5 hex head screw addresses critical challenges in machinery assembly, structural frameworks, and equipment manufacturing.
