S-93945A039 Length 1 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 Stainless Steel construction, ensuring long-term reliability in harsh industrial environments.
• High-torque installation enabled by the square drive design, reducing cam-out and improving assembly efficiency.
• Secure, flush-mount fastening with a standard flat head and 82° countersink angle, ideal for smooth sheet metal surfaces.
• Effortless thread forming with pointed tip and A/AB type design, minimizing installation effort and preventing material cracking.
• Full-length threading for maximum grip and holding power across the entire 1-1/2" length in sheet metal applications.
• Precision compatibility with a No. 21 drill bit (0.159" diameter), ensuring accurate pilot holes and reduced assembly errors.
• Environmental and regulatory compliance with RoHS 3 and REACH standards, supporting sustainable and safe manufacturing practices.

Professional Applications & Engineering Value

These No. 10-12 thread forming tapping screws are engineered specifically for sheet metal applications, where material integrity and fastener reliability are critical. The 18-8 stainless steel composition provides excellent resistance to rust and corrosion, making them suitable for outdoor, marine, or chemically exposed environments. The flat head with an 82° countersink angle ensures a smooth, flush finish, reducing snagging and improving aesthetic appeal in visible assemblies. With a square drive for high torque transfer and a thread forming design, these screws create strong, permanent threads in ductile materials without pre-tapping, saving time and labor in high-volume production. The fully threaded shank and pointed tip facilitate quick starts and consistent engagement, minimizing the risk of cross-threading and enhancing joint strength in sheet metal fastening projects.

Specification Summary & Compliance

This product adheres to standard inch measurements with a No. 10 screw size and 12 threads per inch, ensuring precise fit and performance. The thread forming (A/AB type) tapping method and right-hand thread direction comply with industry norms for sheet metal screws. Manufacturing and material specifications confirm compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, guaranteeing the absence of hazardous substances and supporting environmental safety in industrial applications.
