Key Features & Benefits at a Glance
- Superior corrosion resistance with zinc-plated steel construction, ensuring long-lasting performance in demanding industrial environments.
- Effortless installation thanks to the thread-cutting design (Type F) that taps its own mating threads in materials like aluminum, brass, cast iron, and sheet metal.
- High-torque capability and secure fastening provided by the external hex drive and flanged head, which distributes clamping force over a wider area.
- Maximum grip and holding power from the fully threaded coarse (UNC) design, preventing loosening under vibration and stress.
- Streamlined assembly process with a clear No. 11 drill bit size recommendation, reducing setup time and errors.
- Guaranteed reliability and interchangeability as it meets the stringent dimensional and performance requirements of ASME B18.6.3.
- Safe for global use with RoHS 3 compliance, ensuring the screw is free from hazardous substances.
Professional Applications & Engineering Value
This 12-24 UNC tapping screw is engineered to solve common fastening challenges in metalworking and assembly. Its thread-cutting feature (Type F) eliminates the need for pre-tapped holes, significantly reducing labor and production time when joining aluminum, brass, cast iron, and sheet metal. The zinc-plated steel material provides a durable barrier against rust and corrosion, extending the service life of your products in harsh conditions. The combination of a coarse UNC thread and flanged head ensures a vibration-resistant connection and superior clamp load distribution, preventing material damage and joint failure. This makes it an indispensable component for industrial machinery, construction frameworks, and automotive assemblies where reliability is non-negotiable.
Specification Summary & Compliance
This screw features a 12-24 UNC coarse thread with standard Class 2A tolerances, ensuring precise fit and interchangeability. It is manufactured in compliance with the ASME B18.6.3 specification (SAE J933), guaranteeing consistent quality and performance. The product is also RoHS 3 (2015/863/EU) Compliant, adhering to environmental and safety regulations for hazardous substance restrictions.
