S-90198A280 Length 1 3/4" Tapping Screws

Key Features & Benefits at a Glance

• Exceptional corrosion resistance with 316 stainless steel construction, ideal for harsh industrial environments and outdoor applications.
• Superior thread-forming capability with Type A/AB design creates strong, reliable threads in sheet metal without pre-tapping, reducing installation time.
• Optimized for sheet metal applications, designed to securely fasten materials up to 0.025" thick with maximum holding power.
• Efficient Phillips drive (No. 2 size) allows for quick installation with standard tools, minimizing cam-out and improving workflow.
• Fully threaded shank ensures consistent engagement along the entire length for enhanced load distribution and vibration resistance.
• Flat head with standard 82° countersink provides a flush finish, preventing snagging and improving safety in assembled products.
• Compliance with RoHS 3 and REACH regulations guarantees environmental safety and meets global industrial standards for hazardous substances.

Professional Applications & Engineering Value

These 316 stainless steel tapping screws are engineered to address common challenges in sheet metal fabrication, such as material fatigue and corrosion in demanding environments. The thread forming technology (Type A/AB) displaces material to create precise, durable threads without chips, eliminating the need for separate tapping operations and reducing assembly costs. The fully threaded design and pointed tip ensure easy starts and uniform stress distribution, preventing loosening under vibration. With a Phillips drive and flat head profile, they offer reliable fastening in HVAC systems, electronic enclosures, and automotive panels, where corrosion resistance and long-term performance are critical. This makes them a cost-effective solution for industries requiring high-strength, compliant fasteners.

Specification Summary & Compliance

This product features a No. 8 screw size with a 0.164" thread diameter and 15 threads per inch, ensuring precise fit in pre-drilled holes (recommended drill bit size: No. 29). The flat head conforms to standard 82° countersink angles for seamless integration. Manufactured to thread forming standards (Type A/AB) with right-hand threading, it complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, affirming adherence to environmental and safety requirements in industrial applications.
