S-90048A305 Length 3" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction, ensuring long-lasting performance in demanding industrial environments.
• Efficient thread forming design creates strong, permanent threads in sheet metal without pre-tapping, reducing installation time and labor costs.
• Secure flush mounting with a standard flat head and 82° countersink angle for a smooth, professional finish that prevents snagging.
• Reliable drive engagement provided by the Phillips No. 3 drive, minimizing cam-out and enabling consistent torque application.
• Full-length threading ensures maximum grip and holding power across the entire 3" length, ideal for varied material thicknesses.
• Precision compatibility with 3/16" drill bits and 0.025" maximum drilling thickness, offering dependable performance in standard sheet metal applications.
• Compliance with environmental regulations including RoHS 3 and REACH, making them suitable for global supply chains and eco-conscious projects.

Professional Applications & Engineering Value

These No. 12 x 3" zinc-plated steel tapping screws are engineered to address common challenges in sheet metal fastening, such as material fatigue and loosening under vibration. The thread forming (Type A/AB) technique displaces metal to form robust internal threads, eliminating the need for nuts or washers and reducing assembly steps. Made from durable zinc-plated steel, they resist rust and wear in humid or outdoor settings, while the Phillips flat head and 82° countersink provide a seamless fit that enhances structural integrity. Ideal for HVAC, automotive, and electronics enclosures, these fully threaded screws deliver consistent clamping force, preventing joint failure and ensuring long-term reliability in industrial applications.

Specification Summary & Compliance

This product adheres to standard inch measurements with a thread diameter of 0.216" and approximately 11 threads per inch, ensuring precise fit. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming the absence of hazardous substances. The screw features a right-hand thread, fully threaded shank, and pointed tip for easy insertion, meeting common industry requirements for sheet metal fasteners without specific callouts for ASME or ISO tolerances, but built for reliable performance in typical applications.
