S-97349A416 Length 5/16" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction, ensuring long-term reliability in humid or demanding environments
• Efficient thread forming design creates strong, permanent threads in plastic materials without pre-tapping, reducing assembly time and labor costs
• Optimized for plastic applications with blunt tip and DST thread type to prevent material cracking and ensure secure fastening
• Enhanced drive engagement with Phillips No. 1 drive style providing reliable torque transfer and reduced cam-out during installation
• Full threading along 5/16" length delivers maximum grip and holding power throughout the entire fastener engagement
• Comprehensive regulatory compliance with RoHS 3 and REACH standards, making them suitable for global industrial applications
• Precision-matched drilling compatibility with No. 44 drill bit (0.086" diameter) for optimal hole preparation and installation efficiency

Professional Applications & Engineering Value

This No. 4-24 thread forming screw delivers exceptional engineering value for plastic assembly applications where material integrity and corrosion resistance are critical. The 18-8 stainless steel construction provides excellent durability against environmental factors, while the thread forming technology (DST type) eliminates the need for separate tapping operations in thermoplastics and other plastic materials. The blunt tip design prevents stress concentration and material splitting, making it ideal for thin-walled plastic components. With 24 threads per inch precision and fully threaded shank, this Phillips pan head tapping screw ensures uniform stress distribution and reliable performance in automotive trim, electronic enclosures, and consumer product assemblies where vibration resistance and long-term fastening security are essential.
