S-91515A660 Length 4" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction for extended service life in demanding industrial environments
• Enhanced fastening stability through the wide flanged truss head design that distributes load over a larger surface area
• Efficient installation with the integrated drilling tip that eliminates pre-drilling requirements in steel and sheet metal up to 1/4" thickness
• Reliable thread formation using thread forming BSD technology that creates strong, vibration-resistant connections
• Optimized drive performance with No. 3 Phillips drive for secure tool engagement and reduced cam-out during installation
• Maximum grip strength through fully threaded design that provides continuous engagement along the entire 4" length
• Regulatory compliance assurance with RoHS 3 certification for environmentally responsible manufacturing standards

Professional Applications & Engineering Value

These 1/4"-14 zinc-plated steel tapping screws deliver exceptional engineering value in steel and sheet metal applications where vibration resistance and structural integrity are critical. The thread forming BSD technology creates precise mating threads without chip removal, eliminating contamination risks in electrical enclosures, HVAC systems, and machinery assemblies. The flanged truss head design provides superior clamping force distribution, preventing material distortion in thin-gauge applications while the integrated drilling tip streamlines installation by combining drilling and tapping operations. This comprehensive solution addresses common industrial challenges including reduced installation time, improved joint reliability, and long-term corrosion protection in harsh operating environments.

Specification Summary & Compliance

These tapping screws feature precision 1/4"-14 fully threaded design with right-hand thread direction and round shank cross-section. Manufactured to BSD tapping screw standards with Class 2A thread tolerances for consistent performance. The product complies with RoHS 3 (2015/863/EU) regulations, ensuring environmental safety and regulatory adherence for industrial applications. The zinc-plated steel material provides reliable corrosion resistance while maintaining the mechanical strength required for demanding fastening applications in steel and sheet metal substrates.
