Key Features & Benefits at a Glance
- Superior corrosion resistance with zinc-plated steel construction, extending service life in demanding industrial environments.
- High-strength thread cutting action with Type F design creates precise, durable threads in materials like aluminum and cast iron without pre-tapping.
- Secure, vibration-resistant fastening provided by the serrated locking flange, preventing loosening under dynamic loads.
- Efficient installation and high torque capability enabled by the external hex head design for quick assembly with standard tools.
- Reliable coarse UNC threading ensures excellent grip and pull-out resistance in a wide range of base materials.
- Versatile material compatibility for use in aluminum, brass, cast iron, and sheet metal, streamlining inventory for diverse applications.
- Full-length threading maximizes engagement depth and provides consistent clamping force along the entire fastener length.
Professional Applications & Engineering Value
This 3/8"-16 zinc-plated steel flanged tapping screw is engineered to solve critical assembly challenges in metalworking and fabrication. Its thread-cutting (Type F) design eliminates the need for separate tapping operations, significantly reducing installation time and labor costs in aluminum, brass, cast iron, and sheet metal. The serrated locking flange provides a secure, vibration-resistant joint that maintains clamp load in high-stress environments, preventing costly failures and maintenance downtime. The combination of a coarse UNC thread and external hex drive ensures quick, high-torque installation with common tools, making it an ideal industrial fastener for production lines, machinery assembly, and structural metal frames where reliability and efficiency are paramount.
Specification Summary & Compliance
This screw features UNC coarse threads (3/8"-16) with standard thread tolerances. It is manufactured to conform to the ASME B18.6.3 standard (SAE J933), ensuring dimensional accuracy and mechanical performance. The product is also RoHS 3 (2015/863/EU) Compliant, meeting stringent environmental regulations for hazardous substances.
