Key Features & Benefits at a Glance

  • Superior thread cutting performance in aluminum, brass, cast iron, and sheet metal without pre-tapped holes, reducing assembly steps and labor costs.
  • Enhanced corrosion resistance with zinc-plated steel construction, ensuring durability in various industrial environments.
  • Secure fastening with flange design that distributes load evenly, minimizing the risk of loosening under vibration.
  • Easy installation and high torque capability thanks to the external hex drive, allowing for efficient use with standard tools.
  • Reliable coarse UNC threading for quick engagement and strong holding power in coarse-grained materials.
  • Full threading along the shank provides consistent grip and pull-out resistance across the entire length.
  • Compatibility with No. 19 drill bit simplifies hole preparation, speeding up production processes.

Professional Applications & Engineering Value

These 10-24 UNC thread cutting tapping screws are engineered to address common challenges in metalworking and assembly, such as stripping threads and time-consuming tapping operations. Made from zinc-plated steel, they offer excellent corrosion protection, making them ideal for harsh conditions in automotive, machinery, and construction sectors. The coarse thread design and thread cutting feature enable self-tapping in materials like aluminum, brass, cast iron, and sheet metal, reducing the need for separate tapping tools and minimizing assembly errors. With a flange and external hex drive, they ensure secure, vibration-resistant connections, enhancing the longevity and reliability of your structures while streamlining installation workflows.

Specification Summary & Compliance

This screw adheres to Class 2A thread tolerances under the UNC coarse thread standard, ensuring precise fit and interchangeability. It meets ASME B18.6.3 specifications (referencing SAE J933) for dimensional accuracy and performance. Additionally, it is RoHS 3 (2015/863/EU) Compliant, supporting environmental and safety regulations in global supply chains.
