S-90064A587 Length 4" Tapping Screws

Key Features & Benefits at a Glance

• Enhanced corrosion resistance with zinc-plated steel construction for extended service life in demanding environments
• Superior torque transmission through external hex drive design prevents stripping during high-torque installation
• Self-drilling capability with specialized No. 3 drill tip eliminates pre-drilling requirements, reducing installation time by up to 0.187" thickness
• Secure fastening performance with thread forming (BSD) design creates stronger, vibration-resistant connections in steel and sheet metal
• Increased bearing surface from integrated flange distributes load evenly, preventing material damage and pull-through
• Full threading along 4" length ensures maximum grip and holding power throughout the entire fastening area
• Environmental compliance assurance with RoHS 3 certification for safe, regulated use in global markets

Professional Applications & Engineering Value

These No. 12 zinc-plated steel tapping screws deliver exceptional engineering value in steel and sheet metal applications where traditional fasteners fail. The thread forming BSD design creates permanent, high-strength threads in parent material without tapping operations, significantly reducing assembly time and labor costs. The integrated drilling tip with 9/32" length penetrates up to 0.187" thickness, eliminating separate drilling steps while maintaining material integrity. The external hex drive system provides reliable torque transmission for consistent installation, while the flanged design increases clamping area to prevent loosening under vibration. These fully threaded screws with 14 TPI configuration ensure maximum thread engagement for structural stability in HVAC systems, metal framing, and industrial equipment assembly.

Specification Summary & Compliance

Manufactured to precise dimensional standards with 0.216" thread diameter and 14 TPI thread pitch for consistent performance. Features right-hand threading with standard inch measurements and fully threaded shank for complete fastening coverage. Compliant with RoHS 3 (2015/863/EU) regulations for environmental safety and restricted substance control. The thread forming tapping method follows industry-standard BSD specifications for reliable performance in various metal substrates.
