S-90106A557 Length 2" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 410 stainless steel construction, ideal for harsh industrial environments
• High-torque installation capability thanks to the external hex head design for secure fastening
• Eliminates pre-drilling requirements with integrated drilling tip that penetrates up to 0.21" thick materials
• Secure thread formation through cold forming process that creates strong, reliable connections in metal substrates
• Enhanced load distribution from the flanged design that reduces surface pressure and prevents loosening
• Full 2" thread engagement provides maximum holding power across the entire fastener length
• Regulatory compliance assurance with RoHS 3 and REACH standards for global industrial applications

Professional Applications & Engineering Value

These thread forming tapping screws deliver exceptional value in metal fabrication and assembly operations. The 410 stainless steel composition provides excellent strength and corrosion resistance, while the BSD thread forming technology creates precise mating threads without generating chips or debris. The integrated drilling tip (No. 3 type) eliminates secondary drilling operations, significantly reducing installation time and labor costs in steel, stainless steel, and sheet metal applications. The fully threaded design ensures uniform stress distribution, while the flanged hex head offers superior torque transmission and eliminates the need for separate washers. This combination makes them ideal for HVAC systems, electrical enclosures, machinery guards, and structural assemblies where vibration resistance and long-term reliability are critical.

Specification Summary & Compliance

This 1/4"-14 thread forming tapping screw features precision right-hand threads with standard inch measurements. The fastener meets BSD tapping screw specifications with a 3/8" hex head and 0.52" flange diameter for optimal load distribution. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and industrial suitability. The thread forming design creates strong, vibration-resistant connections in various metal substrates without requiring pre-tapped holes.
