S-90315A421 Length 3/8" Tapping Screws

Key Features & Benefits at a Glance

• Exceptional corrosion resistance with 18-8 stainless steel construction, ideal for harsh industrial environments and reducing replacement costs.
• Superior material penetration and holding power through thread forming technology, creating strong, reliable threads in sheet metal without pre-tapping.
• Clean, finished appearance and secure seating with the standard oval head design and 82° countersink angle, preventing snagging and providing a flush surface.
• Efficient and secure installation enabled by the Phillips No. 2 drive, offering good torque transfer and reducing cam-out risks for faster assembly.
• Optimized for standard sheet metal applications with a 0.116" drill bit compatibility and 0.025" maximum drilling thickness, ensuring precise and effective fastening.
• Full-length threading for maximum grip along the entire 3/8" length, providing consistent holding strength throughout the fastened materials.
• Compliance with stringent environmental regulations including RoHS 3 and REACH, ensuring safety and sustainability for global industrial supply chains.

Professional Applications & Engineering Value

These 18-8 stainless steel oval head tapping screws are precision-engineered to address common challenges in sheet metal assembly, such as strip-out and corrosion. The thread forming Type A/AB design displaces material to create robust internal threads, eliminating the need for tapped holes and reducing assembly time and cost. The Phillips drive ensures reliable torque application, while the fully threaded shank and pointed tip facilitate easy starting and deep penetration. Made from durable stainless steel, they resist rust and wear in demanding environments, from HVAC systems to electronic enclosures, providing long-term reliability and reducing maintenance downtime for industrial operations.
