Key Features & Benefits at a Glance
- Superior corrosion resistance with zinc-plated steel construction, extending service life in harsh industrial environments.
- High-torque installation capability due to the 1/4" external hex drive, ensuring secure fastening without stripping.
- Efficient thread-cutting action in materials like aluminum, brass, and cast iron, reducing the need for pre-tapped holes.
- Enhanced holding power from the flanged design, which distributes load and resists pull-out in sheet metal applications.
- Reliable coarse UNC threading for quick assembly and reduced cross-threading risks in high-vibration settings.
- Full threading along the 1/2" length provides consistent grip depth for versatile material thicknesses.
- Compliance with industry standards including ASME B18.6.3 and RoHS 3, ensuring quality and environmental safety.
Professional Applications & Engineering Value
This 8-32 zinc-plated steel flanged hex tapping screw is engineered to address common challenges in industrial assembly, such as material fatigue and corrosion. The thread-cutting design (Type F) allows for self-tapping in aluminum, brass, cast iron, and sheet metal, eliminating the need for separate tapping operations and reducing labor costs. The coarse UNC thread spacing ensures rapid installation and strong holding power, even in high-vibration environments. With a zinc-plated surface, it resists rust and degradation, making it ideal for outdoor or humid conditions. The integrated flange provides a wider bearing surface, preventing loosening and distributing stress effectively, which is critical for maintaining structural integrity in demanding industrial applications.
Specification Summary & Compliance
This screw features precise UNC coarse threads with a size of 8-32 and full threading for consistent performance. It adheres to ASME B18.6.3 specifications (referencing SAE J933) for dimensional accuracy and mechanical properties. The product is RoHS 3 (2015/863/EU) compliant, ensuring it meets environmental regulations without hazardous substances. Designed for use with a No. 26 drill bit (0.147" diameter), it guarantees proper fit and function in specified materials like aluminum and sheet metal.
