Key Features & Benefits at a Glance
- Superior corrosion resistance with zinc-plated steel construction, extending service life in demanding industrial environments
- Enhanced locking stability through flange design with serrations, preventing loosening under vibration and dynamic loads
- Optimized thread engagement with UNC coarse threading and Type F thread cutting design, ensuring secure fastening in aluminum, brass, cast iron, and sheet metal
- Efficient installation with external hex drive and flanged head design, enabling high-torque application without separate washers
- Full-threaded shank design provides consistent clamping force along the entire fastener length for reliable joint integrity
- Precision compatibility with standard No. 11 drill bits (0.191" diameter), streamlining installation processes and reducing preparation time
- Regulatory compliance assurance meeting both ASME B18.6.3 mechanical specifications and RoHS 3 environmental standards
Professional Applications & Engineering Value
These 12-24 UNC thread cutting tapping screws deliver exceptional performance in metalworking applications where traditional fasteners fail. The zinc-plated steel construction provides essential corrosion protection while maintaining high tensile strength for aluminum, brass, cast iron, and sheet metal assemblies. The Type F thread cutting design with coarse UNC threading creates precise mating threads in parent materials without pre-tapping, significantly reducing installation time and labor costs. The flanged hex head with serrations eliminates the need for additional locking washers while providing vibration-resistant fastening critical for automotive, machinery, and structural applications. This combination of features makes these tapping screws ideal for production lines requiring both speed and reliability in metal-to-metal fastening operations.
Specification Summary & Compliance
Manufactured to ASME B18.6.3 specifications with UNC coarse threads (12-24 size) and standard Class 2A tolerances. Features a flanged hex head (0.313" width, 0.194" height) with external hex drive and fully threaded 3/4" length. The thread cutting design (Type F) is optimized for use with No. 11 drill bits (0.191" diameter). Compliant with RoHS 3 (2015/863/EU) environmental standards, ensuring safe use across various industrial sectors.
