Professional Applications & Engineering Value
These zinc-plated steel flanged hex tapping screws deliver exceptional thread-cutting performance in demanding materials including aluminum, brass, cast iron, and sheet metal. The UNC coarse thread design combined with fully threaded construction ensures rapid installation and superior pull-out resistance, eliminating the need for pre-tapped holes in industrial assembly applications. The integrated flange distributes clamping force evenly, preventing surface damage while the external hex drive provides reliable torque transmission for high-strength connections. Engineered for heavy-duty industrial fastening, these screws maintain consistent performance in vibration-prone environments where secure, permanent fastening is critical.
Specification Summary & Compliance
This 5/16"-18 flanged hex tapping screw features UNC coarse threading with standard Class 2A thread tolerances and fully threaded construction. Manufactured to meet ASME B18.6.3 specifications SAE J933, ensuring dimensional accuracy and mechanical performance. Compliant with RoHS 3 (2015/863/EU) environmental regulations, making these screws suitable for global industrial applications requiring restricted substance compliance.
