S-90395A299 Length 1 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction, ensuring long-lasting performance in industrial environments.
• High-strength thread forming design creates durable, secure threads in sheet metal without pre-tapping, reducing assembly time and labor costs.
• Efficient installation with No. 3 square drive and pan head, providing excellent torque transmission and preventing cam-out during driving.
• Full 1-1/2" threading offers maximum grip length and uniform stress distribution for reliable fastening in various material thicknesses.
• Precision-engineered pointed tip facilitates easy starting and alignment, minimizing damage to sheet metal surfaces during installation.
• Optimized for 3/16" drill bits with clear drilling specifications, ensuring consistent hole preparation and reducing installation errors.
• Compliance with international standards including RoHS 3 and REACH, guaranteeing safe, environmentally responsible manufacturing for global supply chains.

Professional Applications & Engineering Value

These No. 12 zinc-plated steel tapping screws are specifically engineered for demanding sheet metal applications where reliability and efficiency are critical. The thread forming A/AB type design eliminates the need for separate tapping operations by cold-forming mating threads directly into the material, significantly reducing assembly steps and potential thread stripping. The combination of zinc-plated corrosion protection and fully threaded right-hand configuration ensures consistent clamping force distribution across the entire fastener length, preventing loosening under vibration in HVAC systems, electrical enclosures, and automotive assemblies. The pan head with No. 3 square drive provides superior torque transmission compared to Phillips drives, minimizing tool slippage and damage to fastener heads in high-volume production environments.

Specification Summary & Compliance

These thread forming tapping screws feature precision No. 12 screw size with 0.216" thread diameter and 11 threads per inch in right-hand direction. Manufactured to A/AB tapping screw type standards with fully threaded 1-1/2" length and standard class 2A thread tolerances for consistent performance. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and regulatory acceptance for industrial applications worldwide.
