S-95115A125 Length 1 1/4" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction, ensuring long-term reliability in harsh industrial environments.
• Efficient thread forming design with A/AB type tapping, creating strong threads in sheet metal without pre-tapping, reducing installation time and labor costs.
• Full threading along the 1-1/4" length provides maximum grip and uniform load distribution, preventing loosening under vibration.
• Flat head with standard 82° countersink allows for flush mounting in sheet metal applications, improving aesthetics and safety.
• Drilled spanner drive (No. 8 size) enables secure tool engagement and high-torque installation, minimizing slip and damage risks.
• Compliance with RoHS 3 and REACH regulations ensures environmental safety and global market acceptance for your products.
• Optimized for 0.025" maximum drilling thickness with precise No. 29 drill bit compatibility, delivering consistent performance in thin sheet metal assemblies.

Professional Applications & Engineering Value

These No. 8 flat head tapping screws are engineered to address common challenges in sheet metal fabrication, such as material fatigue and corrosion. Made from 18-8 stainless steel, they offer excellent resistance to rust and oxidation, ideal for outdoor or humid conditions. The thread forming design with 15 TPI and pointed tip cuts installation effort by forming threads as they're driven, eliminating the need for separate tapping operations. This fully threaded configuration ensures maximum holding power across the entire length, critical for maintaining joint integrity in vibrating machinery or structural panels. The flat head profile with 82° angle sits flush, reducing snag hazards and providing a clean finish in HVAC systems, electronic enclosures, and automotive components. By combining precise drilled spanner drive mechanics with robust material properties, these screws streamline assembly workflows while enhancing durability in demanding industrial settings.

Specification Summary & Compliance

This product features a thread diameter of 0.164" with approximately 15 threads per inch, adhering to standard inch measurements for consistent fit. The flat head design complies with typical industrial profiles, ensuring compatibility with common countersink tools. Manufacturing follows recognized practices for thread forming screws (Type A/AB), providing reliable performance in sheet metal applications. It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming the absence of restricted hazardous substances and supporting sustainable procurement policies.
