S-93945A008 Length 1 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction, ideal for harsh industrial environments and long-term reliability.
• Efficient thread forming design creates strong, permanent threads in sheet metal without pre-tapping, reducing assembly time and labor costs.
• Secure square drive provides excellent torque transmission and minimizes cam-out, ensuring reliable installation and reducing tool wear.
• Optimized for 0.025" maximum drilling thickness in sheet metal applications, delivering precise performance in thin-material assemblies.
• 82° countersink angle and flat head allow for a flush, professional finish that improves safety and aesthetics in final products.
• Fully threaded shank maximizes grip and holding power across the entire length, enhancing joint strength in demanding applications.
• Compliance with RoHS 3 and REACH regulations ensures environmental safety and global market acceptability for your products.

Professional Applications & Engineering Value

These No. 6-18 thread forming tapping screws are engineered specifically for sheet metal applications, where traditional fastening methods often lead to stripped threads or material failure. The 18-8 stainless steel material provides excellent resistance to oxidation and corrosion, making these flat head screws suitable for outdoor equipment, HVAC systems, and electronic enclosures. The thread forming (A/AB type) design displaces material rather than cutting it, resulting in stronger threads with improved resistance to vibration loosening. Combined with the square drive and 82° countersink, these screws ensure quick, secure installations that maintain integrity under dynamic loads, reducing maintenance needs and improving assembly line efficiency in industrial settings.
