S-94195A389 Length 1 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Fast, Efficient Installation: Integrated No. 3 drill tip eliminates pre-drilling, saving significant time and labor costs in aluminum and sheet metal assembly.
• Superior Corrosion Resistance: Made from durable 18-8 Stainless Steel to ensure long-term reliability in demanding environments.
• Secure, Low-Profile Fastening: The flat head with an 82° countersink angle sits flush for a smooth finish and prevents snagging.
• High-Strength Thread Engagement: Thread forming (BSD) method creates strong, durable threads in ductile materials without generating chips.
• Optimized for Material Thickness: A 1-1/2" length and drill tip designed to penetrate up to 0.14" thick materials effectively.
• Reliable Drive Performance: The Phillips No. 3 drive offers good torque transfer and cam-out resistance during installation.
• Full Compliance for Global Use: Meets RoHS 3 and REACH regulations, ensuring they are safe for restricted substances and suitable for international supply chains.

Professional Applications & Engineering Value

These self-drilling tapping screws are engineered to solve the critical industrial challenge of fastening aluminum and sheet metal efficiently and reliably. The 18-8 stainless steel construction provides excellent resistance to rust and corrosion, which is vital for outdoor enclosures, HVAC systems, and electronic chassis. The thread-forming (BSD) design is particularly valuable as it displaces material to create strong, strip-resistant threads without the risk of loose chips causing electrical shorts or contamination. The combination of a fully threaded shank and a precisely engineered drill tip ensures a single-step operation that reduces assembly time, minimizes tooling requirements, and delivers consistent, high-clamp force joints in high-volume production environments.

Specification Summary & Compliance

This fastener is a No. 12 size with a thread diameter of 0.216" and 14 threads per inch (TPI). It features a standard flat head profile and is fully threaded. The screw conforms to typical inch-series dimensional standards for tapping screws. The product is manufactured to be compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming it is free of hazardous substances and approved for use in regulated markets.
