S-97899A611 Length 1" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 410 stainless steel construction for long-lasting performance in demanding environments
• Self-drilling capability with No. 3 drill tip eliminates pre-drilling requirements, reducing installation time and labor costs
• Maximum drilling capacity of 0.187" thickness enables efficient fastening through steel, stainless steel, and sheet metal applications
• Thread forming design creates stronger, more secure threads in parent material without chip formation
• Integrated flange design provides wider bearing surface for improved load distribution and vibration resistance
• External hex drive ensures high torque transmission and prevents stripping during installation
• White painted head offers both corrosion protection and visual identification for quality control

Professional Applications & Engineering Value

These No. 12 tapping screws with 14 TPI thread forming capability are engineered to solve critical fastening challenges in metal fabrication and assembly operations. The 410 stainless steel composition provides excellent corrosion resistance while maintaining the strength required for structural applications. The self-drilling tip eliminates the need for separate drilling operations, significantly reducing installation time and labor costs in steel, stainless steel, and sheet metal applications. The flanged design distributes clamping force over a wider area, preventing material deformation and maintaining joint integrity under vibration and dynamic loads. This combination of features makes these thread forming screws ideal for HVAC systems, electrical enclosures, metal framing, and industrial equipment assembly where reliability and efficiency are paramount.

Specification Summary & Compliance

These flanged tapping screws feature a No. 12 size with 0.216" thread diameter and 14 TPI right-hand threads, designed to BSD standards for consistent performance. The thread forming design creates secure fastening without chip removal, while the 1" length provides versatile application coverage. The screws maintain precise dimensional tolerances suitable for industrial applications and are fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring they meet the latest international standards for hazardous substance restrictions.
