S-90822A533 Length 3 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 410 stainless steel construction for long-lasting performance in demanding industrial environments
• Efficient installation through combined drilling and thread forming action, eliminating need for pre-drilling in materials up to 0.187" thickness
• Enhanced grip and stability with flanged hex head design that distributes clamping force and prevents pull-through
• Reliable thread engagement with thread forming technology that creates strong, vibration-resistant connections in steel and sheet metal
• Optimized drive efficiency featuring external hex drive for high-torque application and secure fastening
• Full-length threading ensures maximum holding power across the entire 3-1/2" length for superior joint integrity
• Regulatory compliance meeting RoHS 3 and REACH standards for safe use in industrial applications worldwide

Professional Applications & Engineering Value

These No. 12 flanged tapping screws deliver exceptional engineering value by combining 410 stainless steel durability with advanced thread forming technology. The integrated drilling tip design (No. 3 tip type) penetrates up to 0.187" thickness in steel, stainless steel, and sheet metal applications, eliminating costly pre-drilling operations while creating permanent, vibration-resistant threads. The flanged hex head provides superior bearing surface that prevents pull-through and maintains clamp load under dynamic conditions. With 14 TPI right-hand threading and BSD screw type compatibility, these screws offer reliable performance in structural assemblies, metal framing, and industrial equipment where corrosion resistance and installation efficiency are critical.

Specification Summary & Compliance

This No. 12 size tapping screw features a 3-1/2" length with 0.216" thread diameter and 14 TPI thread pitch, manufactured to BSD tapping screw standards with thread forming technology. The external hex drive (0.313" head width) ensures secure tool engagement, while the flanged design (0.432" diameter) provides enhanced load distribution. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, meeting international environmental and safety standards for industrial fastener applications.
