S-90065A192 Length 3/8" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction, ideal for harsh industrial environments and outdoor applications.
• Efficient thread forming design creates strong, permanent threads in sheet metal without pre-tapping, reducing assembly time and labor costs.
• Flush, secure seating with the undercut flat head and 82° countersink angle, preventing snagging and providing a smooth finished surface.
• Reliable drive engagement from the No. 2 Phillips drive, minimizing cam-out and ensuring consistent torque application during installation.
• Full-length threading maximizes grip and holding power across the entire 3/8" length in sheet metal assemblies.
• Compliance with major regulations including RoHS 3 and REACH, ensuring safety and environmental responsibility for global supply chains.
• Optimized for precision with a pointed tip and specified No. 29 drill bit, enabling accurate alignment and clean hole creation in materials up to 0.025" thick.

Professional Applications & Engineering Value

This Type AB thread forming screw is engineered to solve common fastening challenges in sheet metal fabrication. Its 18-8 stainless steel composition provides excellent resistance to oxidation and chemical exposure, making it suitable for HVAC systems, electronic enclosures, and automotive panels. The thread forming (tapping) action cold-forms the material, resulting in zero chip production and stronger thread engagement that resists vibration loosening. The undercut flat head design ensures a flush fit, eliminating protrusions that could interfere with adjacent components. Paired with a standard No. 2 Phillips drive, it offers a balance of widespread tool compatibility and efficient installation, reducing the risk of stripped heads and improving production line throughput in high-volume manufacturing settings.

Specification Summary & Compliance

This screw adheres to standard inch measurements with a No. 8 screw size, 0.164" thread diameter, and 18 threads per inch. The fully threaded right-hand design and round shank ensure consistent performance. It is manufactured to precise dimensional standards for reliable interchangeability. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming it is free of restricted hazardous substances and safe for use in regulated industries.
