S-90048A244 Length 5/8" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction, ensuring long-term reliability in demanding industrial environments.
• Efficient thread-forming design (Type A/AB) creates strong, permanent threads in sheet metal without pre-tapping, reducing installation time and labor.
• Optimized 82° countersink angle allows the flat head to sit flush with surfaces, providing a clean finish and preventing snagging.
• Full threading along the 5/8" length maximizes grip and holding power across the entire material thickness for secure fastening.
• Phillips No. 2 drive offers widespread tool compatibility and controlled torque application, minimizing cam-out and driver slippage.
• Precision-matched No. 21 drill bit size (0.159" diameter) ensures proper hole fit, reducing the risk of material cracking or loose fittings.
• Compliance with RoHS 3 and REACH regulations guarantees environmentally safe and legally approved use in global markets.

Professional Applications & Engineering Value

These No. 10 x 5/8" zinc-plated steel tapping screws are engineered to address common challenges in sheet metal fabrication, such as material fatigue and fastener loosening under vibration. The thread-forming tapping method displaces metal to create robust, load-bearing threads without chips, enhancing joint integrity in thin-gauge applications up to 0.025" thickness. The fully threaded right-hand design and pointed tip facilitate quick starts and consistent penetration, while the Phillips flat head with a standard profile ensures a seamless, low-profile installation. Ideal for HVAC systems, electronic enclosures, and automotive panels, these screws deliver reliable industrial-grade fastening with minimal risk of strip-out or corrosion, supported by precise 82° countersink angles for optimal flush seating.

Specification Summary & Compliance

This product adheres to standard inch measurements with a thread diameter of 0.19" and 12 threads per inch, ensuring compatibility with common sheet metal thicknesses. The flat head features a diameter of 0.362" and height of 0.116", designed for a standard profile. Manufactured to meet RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, these screws are free of hazardous substances, supporting sustainable and safe industrial use. The thread-forming Type A/AB specification guarantees consistent performance without the need for additional tapping steps.
