S-90822A155 Length 1 1/4" Tapping Screws

Key Features & Benefits at a Glance

• Enhanced corrosion resistance with 410 stainless steel construction for long-lasting performance in demanding environments
• Superior installation efficiency with integrated drilling tip that eliminates pre-drilling, saving time and labor costs
• Maximum material penetration capable of drilling through up to 0.09" thickness in steel, stainless steel, and sheet metal
• Secure fastening with excellent pull-out resistance through thread forming design that creates strong, permanent threads in base materials
• High-torque installation capability with external hex drive and flanged head design for superior grip and stability
• Reliable thread engagement with fully threaded shank and consistent 20 threads per inch for uniform load distribution
• Environmental compliance assurance meeting RoHS 3 and REACH regulations for sustainable manufacturing practices

Professional Applications & Engineering Value

These No. 6-20 self-drilling tapping screws deliver exceptional engineering value in metal fabrication and construction applications. The 410 stainless steel composition provides excellent corrosion resistance while maintaining high strength, making them ideal for outdoor and harsh environment applications. The thread forming design (BSD type) creates strong, permanent threads in base materials without chip formation, eliminating contamination concerns in sensitive environments. The integrated drilling tip with 9/64" length and No. 2 geometry ensures clean penetration through steel, stainless steel, and sheet metal up to 0.09" thickness, significantly reducing installation time and labor costs. The flanged hex head with external drive provides superior torque transmission and eliminates the need for separate washers, creating a secure, vibration-resistant connection that maintains integrity under dynamic loads.

Specification Summary & Compliance

This thread forming screw features a No. 6-20 thread size with 0.138" thread diameter and 20 threads per inch, manufactured to precise dimensional standards. The BSD tapping screw type utilizes right-hand threading with fully threaded round shank for consistent performance. The product maintains RoHS 3 (2015/863/EU) compliance and REACH (EC 1907/2006) compliance, ensuring environmental responsibility and regulatory adherence for industrial applications requiring certified components.
