S-90203A519 Length 1 1/4" Tapping Screws

Key Features & Benefits at a Glance

• Eliminates pre-drilling requirements with integrated No. 3 drill tip, saving significant labor time and costs in steel, stainless steel, and sheet metal assemblies
• Superior corrosion resistance provided by 410 Stainless Steel construction, ensuring long-term reliability in demanding industrial environments
• Enhanced torque transmission and strip resistance through square drive design, allowing for secure installation and reduced fastener failure
• Optimized material displacement with BSD thread forming technology, creating strong, vibration-resistant threads without chip removal
• Maximum material penetration capability with 1/4" drill tip length, effectively drilling through materials up to 0.15" thick
• Secure fastening across full length thanks to fully threaded 1-1/4" design, providing consistent holding power throughout the engagement area
• Compliance with international environmental standards including RoHS 3 and REACH, ensuring regulatory acceptance for global manufacturing operations

Professional Applications & Engineering Value

These No. 10-16 self-drilling tapping screws deliver exceptional value in metal fabrication and assembly operations by combining drilling and tapping into a single operation. The 410 Stainless Steel composition provides excellent strength and corrosion resistance, while the BSD thread forming design creates precise, high-strength threads in parent materials without generating chips that could interfere with electrical components or moving parts. The square drive and pan head configuration ensures maximum torque transfer during installation, reducing the risk of driver cam-out and damaged fastener heads. Particularly valuable in sheet metal applications, HVAC systems, and electrical enclosures, these screws eliminate the time-consuming separate drilling step while maintaining consistent performance across steel and stainless steel substrates up to 0.15" thickness.

Specification Summary & Compliance

These industrial fasteners feature precision No. 10-16 thread with 0.19" diameter and 16 threads per inch in right-hand orientation. The BSD thread forming tapping method ensures consistent thread engagement without material chips. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, making them suitable for global industrial applications requiring strict material compliance. The 1-1/4" fully threaded length with No. 3 drill tip provides reliable performance in standardized assembly processes.
