S-90064A590 Length 1 1/4" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction for extended service life in demanding environments
• Efficient installation with self-drilling tip that eliminates pre-drilling, saving time and labor costs
• Maximum material penetration capable of drilling through up to 0.187" thick steel and sheet metal
• Enhanced torque transmission through external hex drive design for secure fastening without slippage
• Secure thread formation with BSD thread forming technology that creates strong, vibration-resistant connections
• Integrated flange design provides wider bearing surface for improved load distribution and stability
• Full threading ensures consistent engagement along the entire length for maximum holding power

Professional Applications & Engineering Value

These No. 12 zinc-plated steel tapping screws are engineered specifically for steel and sheet metal applications where drilling and fastening operations need to be combined for efficiency. The thread forming design creates precise mating threads in the base material without chip formation, eliminating the risk of contamination in electrical enclosures or HVAC systems. The drilling tip with 9/32" length and No. 3 point configuration provides reliable penetration through materials up to 0.187" thick, while the external hex drive ensures maximum torque application during installation. These flanged screws are particularly valuable in assembly lines where speed, reliability, and consistent performance are critical for production throughput and joint integrity in structural frameworks, machinery guards, and metal fabrication projects.

Specification Summary & Compliance

These thread forming tapping screws feature a No. 12 screw size with 0.216" thread diameter and 14 TPI right-hand threading, fully threaded along the 1-1/4" length. Manufactured to BSD standards for thread forming applications, they ensure precise fit and reliable performance in steel and sheet metal substrates. The product is RoHS 3 (2015/863/EU) compliant, meeting environmental regulations for hazardous substance restrictions, making them suitable for global industrial applications requiring environmental compliance.
