S-90415A330 Length 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel and protective coating, ensuring long-term reliability in harsh industrial environments.
• Efficient self-drilling capability with a No. 2 drill tip that penetrates up to 0.098" thick materials, eliminating the need for pre-drilling and reducing installation time.
• Strong, secure fastening through thread-forming BSD technology, which creates durable, vibration-resistant threads in steel, stainless steel, and sheet metal.
• Wide compatibility with a fully threaded No. 8-18 right-hand design, providing consistent holding power across various applications.
• Easy installation thanks to the Phillips pan head and No. 2 drive, allowing for quick, tool-friendly assembly without slippage.
• Environmental compliance with RoHS 3 and REACH standards, ensuring safe, sustainable use in regulated industries.
• Optimized for high-stress applications with a rounded pan head profile that distributes load evenly and resists stripping.

Professional Applications & Engineering Value

These corrosion-resistant coated stainless steel tapping screws are engineered to address common challenges in metalworking and assembly, such as time-consuming pre-drilling and fastener failure due to rust or vibration. The thread-forming BSD design cuts precise, strong threads directly into steel, stainless steel, and sheet metal, enhancing joint integrity and reducing the risk of loosening under dynamic loads. The integrated No. 2 drill tip streamlines workflows by allowing direct penetration into materials up to 0.098" thick, making them ideal for HVAC, automotive, and construction applications where speed and durability are critical. Combined with a Phillips pan head for easy drive engagement, these screws deliver reliable performance in demanding environments, minimizing maintenance and downtime.
