• Full threading along 2" length provides maximum thread engagement and uniform stress distribution
• Industry-standard compliance guarantees consistent quality and interchangeability across industrial applications

Professional Applications & Engineering Value

Engineered for demanding industrial applications, these thread cutting flange screws solve critical assembly challenges in aluminum, brass, cast iron, and sheet metal components. The zinc-plated steel construction provides essential corrosion protection while maintaining high tensile strength. The F-type thread cutting design with blunt tip eliminates the need for separate tapping operations, significantly reducing installation time and labor costs in high-volume production environments. The integrated flange distributes clamping force evenly, preventing material distortion in thin-section applications. With coarse UNC threading and external hex drive, these screws deliver reliable performance in vibration-prone assemblies while accommodating quick installation with standard tools.
