S-90184A294 Length 3" 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 creates strong, permanent threads in sheet metal without the need for a pre-tapped hole, reducing assembly time.
• Optimized for high-strength fastening in sheet metal up to 0.025" thick, ensuring reliable and vibration-resistant connections.
• Efficient installation with a standard Phillips No. 2 drive, providing good torque transfer and reducing the risk of cam-out.
• Full-length threading along the 3" length maximizes grip and holding power across the entire fastened material.
• Wide compatibility with standard No. 29 (0.136") drill bits, simplifying the preparation process for maintenance and production teams.
• Compliant with major environmental regulations including RoHS 3 and REACH, ensuring safety and suitability for global supply chains.

Professional Applications & Engineering Value

This thread forming tapping screw is engineered to solve common fastening challenges in sheet metal assemblies, such as material stripping and weak thread engagement. The 316 stainless steel material provides outstanding resistance to chlorides and acidic conditions, making it perfect for marine, chemical processing, and food industry equipment. Its A/AB type thread and pointed tip allow for easy starting and smooth, high-pressure forming of threads in ductile metals, creating a tight, secure fit that resists loosening under dynamic loads. By eliminating the need for separate nuts or tapped holes, this Phillips pan head screw streamlines production, reduces component count, and lowers overall assembly costs while maintaining high corrosion resistance and structural integrity in demanding applications.

Specification Summary & Compliance

This screw conforms to standard inch dimensions: No. 8 size with a 0.164" thread diameter and 15 threads per inch. The pan head features a diameter of 0.322" and height of 0.115". It is designed as a thread forming type A/AB tapping screw with a right-hand thread direction and is fully threaded. Manufacturing and material compliance include RoHS 3 (2015/863/EU) and REACH (EC 1907/2006), ensuring it is free of restricted hazardous substances and safe for industrial use.
