S-92970A222 Length 1 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 410 stainless steel construction, ensuring long-term reliability in harsh industrial environments
• Enhanced drilling efficiency with specialized drill tip that penetrates up to 0.187" thick steel, stainless steel, and sheet metal without pre-drilling
• Tamper-resistant security through T27 Torx drive design, providing added protection against unauthorized removal in sensitive applications
• Optimized thread engagement with fully threaded No. 12 size and 14 threads per inch, delivering superior holding power in metal substrates
• Time-saving installation combining thread-forming tapping method with self-drilling capability for reduced assembly steps and labor costs
• Secure rounded head profile that sits flush against surfaces while minimizing stress concentration points
• Regulatory compliance assurance meeting RoHS 3 and REACH standards for environmentally responsible manufacturing

Professional Applications & Engineering Value

These 410 stainless steel self-drilling tapping screws solve critical industrial fastening challenges by eliminating the need for separate drilling and tapping operations. The specialized drill tip design with No. 3 point configuration and 9/32" length efficiently penetrates steel, stainless steel, and sheet metal up to 0.187" thick, while the thread-forming A/AB type creates precise mating threads that resist vibration loosening. The T27 tamper-resistant Torx drive provides superior torque transmission compared to conventional drives, reducing cam-out incidents and tool wear. This combination of features makes these right-hand threaded fasteners ideal for HVAC systems, metal fabrication, electrical enclosures, and industrial equipment assembly where corrosion resistance, security, and installation efficiency are paramount.

Specification Summary & Compliance

These No. 12 x 1-1/2" tapping screws feature precision thread forming (Type A/AB) design with standard inch measurements including 0.216" thread diameter and 14 threads per inch. The fully threaded configuration ensures maximum engagement across the entire 1-1/2" length. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming environmental responsibility and material safety. The rounded head profile with 0.425" diameter and 0.156" height provides optimal clamping distribution while the specialized drill tip maintains consistent performance across specified metal thicknesses.
