Key Features & Benefits at a Glance

  • Superior corrosion resistance for extended service life in harsh environments, thanks to the ultra-corrosion-resistant coated alloy steel construction
  • Eliminates pre-drilling and speeds up installation with its integrated drilling tip, designed to penetrate up to 0.187" thick aluminum and sheet metal
  • Enhanced torque transmission and stripping resistance provided by the external hex drive style, ensuring secure and efficient fastening
  • Improved load distribution and seating from the flanged head design, reducing the risk of material damage and loosening under vibration
  • Maximum grip and holding power in thin materials achieved through the fully threaded, thread-forming (BSD) design
  • Reliable, consistent performance with a No. 12 screw size, 14 TPI, and right-hand thread direction, ensuring compatibility and predictable behavior
  • Streamlined inventory by using a single screw for both aluminum and sheet metal applications

Professional Applications & Engineering Value

This flanged hex head tapping screw is engineered to solve common fastening challenges in aluminum and sheet metal fabrication. The ultra-corrosion-resistant alloy steel material prevents rust and degradation, critical for outdoor enclosures, HVAC systems, and electrical cabinets. Its thread-forming (BSD) design and drilling tip create precise, strong threads in ductile materials without pre-tapping, eliminating drill bit breakage and misalignment issues. The external hex drive allows for high-torque installation with standard tools, reducing assembly time. The fully threaded shank and flanged head work together to distribute clamp load over a wider area, preventing pull-through in thin-gauge materials and providing vibration resistance in dynamic applications, making it an ideal tapping screw for demanding industrial assemblies.

Specification Summary & Compliance

This screw conforms to standard inch system specifications: No. 12 size, 0.216" thread diameter, 14 threads per inch (TPI), and a 2" length. The thread-forming (BSD) tapping method and right-hand thread direction ensure reliable performance. Manufacturing adheres to industry standards for dimensional accuracy, including head height (0.194") and width (0.313"), and flange diameter (0.432"). The product is designed for use in materials up to 0.187" thickness and is compliant with relevant industrial fastening standards. Materials and coatings are selected to meet RoHS and REACH environmental directives.
