S-90203A517 Length 2" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 410 Stainless Steel construction for extended service life in demanding industrial environments
• Self-tapping efficiency through thread forming technology that creates strong, permanent threads without pre-drilling
• Enhanced drilling performance with specialized drill tip design that penetrates up to 0.098" thick steel and sheet metal
• Secure installation and removal with square drive system providing superior torque transmission and reduced cam-out
• Maximum holding power through fully threaded design that distributes load evenly across the entire fastener length
• Reliable industrial compliance meeting RoHS 3 and REACH environmental standards for global manufacturing applications
• Optimized for metal applications with BSD tapping screw design specifically engineered for steel, stainless steel, and sheet metal

Professional Applications & Engineering Value

These No. 8 x 2" 410 Stainless Steel tapping screws deliver exceptional value in metal fabrication and assembly operations. The thread forming technology eliminates the need for separate tapping operations, significantly reducing installation time and labor costs while creating stronger, more reliable threads that resist vibration loosening. The integrated drilling tip with 3/16" length penetrates various metal thicknesses up to 0.098", making them ideal for sheet metal applications, HVAC systems, and industrial equipment assembly. The pan head design with square drive ensures secure fastening in high-torque applications, while the fully threaded configuration provides consistent clamping force across the entire engagement length. Manufactured from 410 Stainless Steel, these screws maintain integrity in corrosive environments common to industrial and outdoor applications.

Specification Summary & Compliance
