Key Features & Benefits at a Glance
- Superior corrosion resistance with zinc-plated steel construction for extended service life in harsh industrial environments.
- High-strength thread cutting action (Type F) creates precise mating threads in materials like aluminum and cast iron, eliminating the need for pre-tapped holes.
- Efficient power transfer and installation enabled by the external hex head design, allowing for high torque application with standard tools.
- Enhanced load distribution and retention provided by the integrated flange, reducing the risk of loosening under vibration.
- Reliable coarse UNC threading (12-24) ensures quick, deep engagement and strong holding power in a variety of base materials.
- Full threading with a blunt tip offers consistent grip along the entire 5/8" length for a secure and robust fastening point.
- Guaranteed dimensional accuracy and quality, manufactured to meet the rigorous ASME B18.6.3 standard for dependable performance.
Professional Applications & Engineering Value
This zinc-plated steel tapping screw is engineered to solve critical fastening challenges in metalworking and fabrication. Its thread cutting design allows it to form strong, clean threads directly in aluminum, brass, cast iron, and sheet metal, streamlining assembly by removing the separate tapping operation. The flanged hex head provides a larger bearing surface, which helps prevent pull-through in softer materials and offers improved resistance to vibrational loosening—a common issue in machinery and equipment. Made from robust steel with a protective zinc coating, this 12-24 UNC coarse thread screw delivers the durability and corrosion resistance required for heavy-duty industrial applications, ensuring long-term reliability and reducing maintenance needs.
Specification Summary & Compliance
This screw features a No. 12 screw size with a 12-24 UNC coarse thread and a diameter of 0.216". It is fully threaded and has a length of 5/8". Manufactured in compliance with ASME B18.6.3 specifications, ensuring precise dimensional tolerances and performance reliability. The product is also RoHS 3 (2015/863/EU) Compliant, confirming it is free from hazardous substances for safe use in various markets.
