Key Features & Benefits at a Glance

  • Superior corrosion resistance with zinc-plated steel construction, extending service life in demanding industrial environments.
  • Efficient thread-cutting action in aluminum, brass, cast iron, and sheet metal, reducing installation time and effort.
  • Enhanced holding power from the flanged design, which distributes load and minimizes material pull-through.
  • Secure, high-torque fastening enabled by the external hex drive, allowing for reliable tightening with standard tools.
  • Wide material compatibility with coarse UNC threads, ensuring strong, durable connections in various substrates.
  • Full threading for maximum grip along the entire 1" length, providing consistent clamping force.
  • Compliance with industry standards including ASME B18.6.3 and RoHS 3, ensuring quality and environmental safety.

Professional Applications & Engineering Value

This 10-24 UNC zinc-plated steel flanged hex tapping screw is engineered to address common challenges in industrial assembly, such as material fatigue and installation inefficiency. Its thread-cutting design allows it to form precise threads in softer materials like aluminum, brass, and sheet metal, eliminating the need for pre-tapped holes and speeding up production. The flanged head increases bearing surface, reducing the risk of damage in thin materials and providing vibration resistance. Made from durable zinc-plated steel, it offers reliable performance in applications ranging from machinery to metal fabrication, ensuring long-term integrity and reducing maintenance costs.

Specification Summary & Compliance

This screw features a No. 10 size with 10-24 UNC coarse threads, fully threaded along a 1" length, and is designed for use with a No. 19 drill bit (0.166" diameter). It meets ASME B18.6.3 specifications (referencing SAE J933) for dimensional accuracy and performance, and is RoHS 3 (2015/863/EU) compliant, ensuring adherence to environmental and safety regulations in industrial settings.
