S-96024A430 1/4"-20 x 1" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 410 stainless steel construction for long-lasting performance in demanding industrial environments
• Excellent thread-forming capability with UNC coarse spacing and thread cutting design ensures secure fastening in brass, cast iron, and sheet metal
• Enhanced installation efficiency through external hex drive and flanged head design provides superior torque transmission and eliminates need for separate washers
• Maximum holding power achieved through fully threaded design that distributes load evenly across the entire fastener length
• Reliable material penetration with blunt tip design prevents material splitting while maintaining structural integrity
• Comprehensive compliance assurance meeting RoHS 3 and REACH environmental standards for global manufacturing applications
• Optimized drill size compatibility with No. 1 drill bit (0.228") recommendation ensures proper hole preparation and thread engagement

Professional Applications & Engineering Value

These 1/4"-20 UNC thread cutting screws deliver exceptional engineering value in industrial fastening applications where material integrity and corrosion resistance are paramount. The 410 stainless steel construction provides excellent strength and durability while the thread cutting design with coarse spacing ensures reliable performance in challenging materials including brass, cast iron, and sheet metal. The flanged hex head design combines the benefits of a washer and screw head, distributing clamp load over a wider area while the external hex drive allows for high-torque installation. This combination addresses common industrial challenges of material fatigue, corrosion-induced failure, and installation efficiency, making these tapping screws ideal for manufacturing equipment, metal fabrication, and assembly operations requiring consistent, long-term fastening solutions.
