Key Features & Benefits at a Glance

  • Self-tapping design eliminates the need for pre-threaded holes, reducing installation time and labor costs in materials like aluminum and sheet metal.
  • Zinc-plated steel construction provides excellent corrosion resistance, ensuring long-term durability and reliability in various industrial environments.
  • UNC coarse threading offers faster installation and superior holding power in softer materials such as brass and cast iron.
  • Phillips No. 2 drive ensures common tool compatibility and reduces cam-out, providing a secure and efficient driving experience.
  • Fully threaded shank maximizes grip and load distribution along the entire length, enhancing joint strength and vibration resistance.
  • Type F thread cutting tip is engineered to create precise, clean threads, minimizing material stress and preventing stripping.
  • Standard pan head with rounded profile offers a low-profile finish and increased bearing surface for secure fastening without sinking.

Professional Applications & Engineering Value

These 10-24 x 5/8" zinc-plated steel tapping screws are engineered to solve common fastening challenges in metalworking and construction. The thread cutting Type F design allows for direct installation into aluminum, brass, cast iron, and sheet metal without pre-tapping, significantly reducing assembly time and tooling requirements. The UNC coarse thread ensures rapid insertion and strong holding power, while the zinc plating protects against rust and corrosion in harsh conditions. Ideal for industrial fastening applications, these screws provide reliable performance in HVAC systems, machinery assembly, and automotive components, where precision and durability are critical. Their compatibility with a No. 17 drill bit further streamlines the process, making them a cost-effective solution for high-volume production.

Specification Summary & Compliance

This product adheres to Class 2A thread tolerances with UNC coarse threading and a right-hand thread direction. It meets ASME B18.6.3 specifications (referencing SAE J933) for dimensional accuracy and performance. Additionally, it is RoHS 3 (2015/863/EU) Compliant, ensuring it is free from hazardous substances and suitable for global manufacturing standards.
