S-90190A207 Length 2 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction, extending service life in demanding industrial environments
• Excellent thread-forming capability for secure, vibration-resistant fastening in sheet metal without pre-tapping
• Optimized Phillips No. 2 drive provides efficient installation with reduced cam-out risk and improved torque transfer
• Full-length threading and pointed tip ensure maximum grip length and easier penetration for consistent holding power
• Pan head design offers a low-profile, rounded finish with good bearing surface for secure sheet metal connections
• Precise dimensional compliance with A/AB tapping screw standards ensures reliable performance and interchangeability
• Environmental regulatory compliance with RoHS 3 and REACH standards for safe use across global industrial applications

Professional Applications & Engineering Value

These No. 8-15 zinc-plated steel tapping screws are engineered specifically for sheet metal applications where reliable fastening is critical. The thread forming technology creates strong, permanent threads in ductile materials without chip removal, eliminating loose debris in sensitive assemblies. The Phillips pan head design provides excellent drive engagement while maintaining a low profile for space-constrained applications. With full-length threading and a pointed tip, these screws penetrate smoothly and maintain consistent clamping force, preventing loosening under vibration - a common challenge in metal fabrication, HVAC systems, and electronic enclosures. The zinc-plated steel construction delivers dependable corrosion protection, making these fasteners suitable for both indoor and outdoor industrial environments.

Specification Summary & Compliance
