Key Features & Benefits at a Glance
- Superior corrosion resistance with zinc-plated steel construction, ensuring long-lasting performance in demanding industrial environments.
- High-torque installation capability thanks to the external hex drive and hex head design, allowing for secure fastening with standard tools.
- Efficient thread cutting in tough materials with Type F tapping screw design and UNC coarse threads, ideal for aluminum, brass, cast iron, and sheet metal.
- Enhanced load distribution and stability from the integrated flange, reducing the need for separate washers and speeding up assembly.
- Full-thread engagement for maximum holding power across the entire 1 1/2" length, providing reliable fastening in various thicknesses.
- Simplified installation process with pre-specified K drill bit (0.281" diameter), ensuring proper hole size for optimal thread formation.
- Assured quality and regulatory compliance meeting ASME B18.6.3 standards and RoHS 3, guaranteeing safety and environmental responsibility.
Professional Applications & Engineering Value
This heavy-duty flanged tapping screw is engineered to address common challenges in metalworking and assembly, such as material fatigue and installation inefficiency. Made from zinc-plated steel, it resists rust and wear, extending service life in harsh conditions. The Type F thread cutting design and UNC coarse threads enable self-tapping in aluminum, brass, cast iron, and sheet metal, eliminating the need for pre-tapped holes and reducing labor time. The external hex drive ensures high torque application without slippage, while the flange provides added stability, preventing loosening under vibration. Ideal for industrial tapping screw applications, it enhances structural integrity and streamlines production workflows.
Specification Summary & Compliance
This screw adheres to Class 2A thread tolerances with UNC coarse spacing and a thread size of 5/16"-18. It is manufactured in compliance with ASME B18.6.3 specifications and is RoHS 3 (2015/863/EU) compliant, ensuring environmental safety. The design includes a blunt tip and fully threaded shank for consistent performance in thread-cutting applications.
