S-92316A847 3/4"-10 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 Grade 8 strength rating and 150,000 psi tensile strength for reliable performance in high-stress applications
• Superior corrosion resistance thanks to black-phosphate steel coating that protects against rust in harsh industrial environments
• Enhanced grip and stability from the integrated flange design that distributes load evenly and eliminates the need for separate washers
• Quick installation and removal with standard external hex drive that accommodates common wrench sizes up to 1 1/8"
• Optimized thread engagement through UNC coarse threading and Class 2A fit that resists vibration loosening in heavy machinery
• Reduced material stress with partially threaded shank design that concentrates strength where needed most
• Long-term durability backed by Rockwell C32 hardness that maintains structural integrity through repeated use

Professional Applications & Engineering Value

Engineered for heavy-duty industrial applications, these Grade 8 hex head screws deliver exceptional performance where failure is not an option. The black-phosphate steel construction provides superior corrosion protection in demanding environments, from manufacturing equipment to structural assemblies. The UNC coarse threading ensures rapid installation and superior resistance to vibration-induced loosening, while the flanged design eliminates washer requirements and provides enhanced bearing surface. With 3/4"-10 thread size and 3" length, these partially threaded screws offer precise load distribution, making them ideal for critical connections in construction machinery, automotive frames, and industrial equipment where 150,000 psi tensile strength is essential for safety and reliability.
