S-90065A107 Length 5/16" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction for long-lasting performance in harsh environments
• Efficient thread forming technology creates strong, permanent threads in sheet metal without pre-tapping requirements
• Optimal sheet metal compatibility designed specifically for materials up to 0.025" thickness with precise No. 44 drill bit pairing
• Secure Phillips drive engagement ensures reliable installation torque and reduces cam-out during assembly
• Standard 82° countersink angle provides flush mounting for clean, professional finishes in sheet metal applications
• Full threading design maximizes grip length and distributes clamping force evenly across the entire fastener
• Environmental compliance assurance meets RoHS 3 and REACH standards for sustainable industrial operations

Professional Applications & Engineering Value

This No. 4-24 thread forming screw delivers exceptional engineering value in sheet metal fabrication and assembly operations. The 18-8 stainless steel composition provides outstanding resistance to oxidation and chemical exposure, making it ideal for HVAC systems, electronic enclosures, and automotive components where environmental durability is critical. The Type A thread forming design eliminates the need for separate tapping operations, reducing assembly time and labor costs while creating strong, vibration-resistant connections. The Phillips flat head configuration with standard 82° countersink ensures seamless integration into metal surfaces, preventing snagging and maintaining aerodynamic profiles. These tapping screws are particularly valuable in high-volume production environments where consistent performance and regulatory compliance are paramount for manufacturing efficiency.
