S-90190A209 Length 3" Tapping Screws

Key Features & Benefits at a Glance

• Enhanced corrosion resistance with zinc-plated steel construction for extended service life in demanding industrial environments
• Superior holding power through thread forming technology that creates strong, permanent threads in sheet metal without chip removal
• Optimized drive efficiency with Phillips No. 2 drive design for secure tool engagement and reduced cam-out during installation
• Maximum material engagement with fully threaded 3" length and 15 threads per inch for consistent fastening throughout the entire screw length
• Reliable seating and distribution thanks to pan head design with 0.322" diameter providing ample bearing surface
• Simplified installation process with pointed tip and precise No. 29 drill bit compatibility for quick, accurate positioning
• Regulatory compliance assurance meeting RoHS 3 and REACH standards for safe, environmentally responsible manufacturing

Professional Applications & Engineering Value

These No. 8 x 3" zinc-plated steel tapping screws deliver exceptional performance in sheet metal applications where vibration resistance and permanent fastening are critical. The thread forming technology eliminates the need for pre-tapped holes while creating stronger, more durable connections by displacing material rather than removing it. This A/AB type tapping screw with Phillips drive ensures reliable installation in HVAC systems, electrical enclosures, and metal fabrication projects. The combination of 0.164" thread diameter and 15 threads per inch provides optimal grip in materials up to 0.025" thickness, making these industrial screws ideal for joining multiple sheet metal layers or attaching components to metal frames with consistent clamping force.

Specification Summary & Compliance

These thread forming screws feature precise Class 2A thread tolerances with right-hand threading and fully threaded design for consistent performance. Manufactured to A/AB tapping screw standards with 0.164" thread diameter and 15 TPI specification. Compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring they meet current industrial safety and environmental standards for global manufacturing applications.
