S-90190A304 Length 3" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction for extended service life in demanding industrial environments
• Efficient thread forming technology creates stronger, more secure fastenings in sheet metal without requiring pre-tapped holes
• Maximum holding power through fully threaded design that distributes load evenly across the entire screw length
• Quick and reliable installation with Phillips No. 3 drive that prevents cam-out and ensures consistent torque application
• Optimized for sheet metal applications with pointed tip for easy starting and 11 threads per inch for superior grip
• Pan head design provides excellent bearing surface while maintaining a low profile for space-constrained applications
• Regulatory compliance assurance meeting RoHS 3 and REACH standards for safe, environmentally responsible manufacturing

Professional Applications & Engineering Value

These No. 12 x 3" zinc-plated steel tapping screws are engineered specifically for sheet metal applications where reliability and durability are paramount. The thread forming technology eliminates the need for pre-tapped holes, creating stronger, more vibration-resistant connections by displacing material rather than removing it. This A/AB tapping screw type with fully threaded design ensures maximum pull-out resistance in thin materials up to 0.025" thickness. The Phillips pan head configuration provides excellent drive engagement while the zinc plating offers corrosion protection for industrial and construction environments. These screws deliver consistent performance in metal fabrication, HVAC systems, electrical enclosures, and automotive assemblies where secure fastening in sheet metal is critical.

Specification Summary & Compliance
