Key Features & Benefits at a Glance
- Superior corrosion resistance with zinc-plated steel construction, extending service life in demanding industrial environments.
- Efficient, self-tapping installation with Type F thread cutting design, eliminating the need for pre-tapped holes in materials like aluminum and sheet metal.
- High-torque fastening capability provided by the external hex/slotted drive and hex head, ensuring a secure, reliable connection.
- Enhanced load distribution and vibration resistance from the integrated flange, improving joint integrity.
- Wide material compatibility for use in aluminum, brass, cast iron, and sheet metal, offering versatile application solutions.
- Quick assembly with coarse UNC threading, reducing installation time and effort.
- Guanteed dimensional consistency and performance, manufactured to meet stringent ASME B18.6.3 specifications.
Professional Applications & Engineering Value
Engineered for robust performance, these 12-24 thread cutting screws are the ideal solution for creating strong, permanent threads in ductile materials. The zinc-plated steel provides a protective barrier against oxidation, crucial for outdoor or high-moisture applications. The Type F tapping screw design, combined with coarse UNC threads, ensures rapid, secure fastening in aluminum, brass, cast iron, and sheet metal, reducing the risk of strip-out and material failure. The external hex/slotted drive offers flexibility for various tools, while the flanged head increases clamping area, distributing force evenly to prevent surface damage and loosening under vibration. This makes them indispensable in automotive, metal fabrication, and machinery assembly, where reliability and speed are paramount.
Specification Summary & Compliance
This screw features a No. 12 size with 12-24 UNC coarse threads, a thread diameter of 0.216", and a length of 3/4". It is designed for use with a No. 11 drill bit (0.191" diameter). The product is fully threaded with a blunt tip and meets ASME B18.6.3 (referencing SAE J933) standards for dimensional accuracy and performance. It is also RoHS 3 (2015/863/EU) Compliant, ensuring it is free from hazardous substances for safe use in regulated industries.
