S-90064A585 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
• Effortless installation through self-drilling tip design that eliminates pre-drilling requirements in steel and sheet metal
• Maximum holding power with fully threaded design ensuring superior grip and vibration resistance throughout the fastener length
• Enhanced load distribution from the integrated flange that provides wider bearing surface and prevents pull-through
• Secure torque application via external hex drive that allows high tightening forces without stripping
• Reliable thread formation with BSD thread forming design that creates strong, permanent threads in base materials
• Environmental compliance meeting RoHS 3 standards for safe, sustainable manufacturing practices

Professional Applications & Engineering Value

This No. 12 zinc-plated steel tapping screw delivers exceptional engineering value by addressing critical installation challenges in steel and sheet metal applications. The combination of thread forming technology and integrated drilling tip eliminates multiple processing steps, significantly reducing assembly time and labor costs. The fully threaded design ensures maximum engagement along the entire 3" length, providing superior resistance to vibration loosening and mechanical stress. With capability to drill through 0.187" maximum thickness materials, this BSD tapping screw maintains structural integrity while the external hex drive facilitates high-torque installation in confined spaces. The zinc-plated finish offers reliable protection against corrosion in industrial environments, making it ideal for HVAC systems, metal fabrication, and structural assemblies where durability and performance are paramount.
