S-92316A211 10-32 x 3/4" IFI 111, SAE J429 High-Strength Grade 8 Steel Flanged Hex Head Screws

Key Features & Benefits at a Glance

• Exceptional Tensile Strength – With 150,000 PSI tensile strength, this screw withstands extreme loads and vibrations, reducing the risk of failure in demanding applications.
• Superior Corrosion Resistance – The black-phosphate steel coating provides a durable barrier against rust and environmental exposure, extending service life in harsh conditions.
• Precise Thread Fit – Class 3A thread fit ensures tight, secure fastening with minimal play, enhancing joint integrity and assembly reliability.
• High-Strength Material Grade – Grade 8 classification and Rockwell C32 hardness offer excellent durability and resistance to wear, ideal for heavy-duty industrial use.
• Integrated Flange Design – The flanged head distributes clamping force evenly, eliminating the need for separate washers and speeding up installation.
• Fine Thread Spacing – UNF fine threads provide superior holding power and vibration resistance compared to coarse threads, ensuring long-term stability.
• Full Threading for Maximum Grip – Fully threaded along the 3/4" length allows for adjustable engagement and secure fastening in various material thicknesses.

Professional Applications & Engineering Value

Engineered for heavy-duty industrial applications, this Grade 8 hex head screw addresses critical challenges in machinery, automotive, and construction sectors. The black-phosphate steel coating combats corrosion in humid or chemically aggressive environments, while the UNF fine thread and Class 3A fit deliver precise, reliable fastening that resists loosening under dynamic loads. The external hex drive and flanged design simplify installation with standard tools, reducing assembly time and minimizing the risk of stripping. Ideal for high-stress joints where 150,000 PSI tensile strength and consistent performance are non-negotiable, this fastener ensures long-term operational safety and reduces maintenance frequency.
