Key Features & Benefits at a Glance
- Superior corrosion resistance with zinc-plated steel construction, extending service life in demanding industrial environments.
- Effortless installation and high thread engagement due to the thread-cutting (Type F) design, reducing assembly time in materials like aluminum and cast iron.
- Enhanced load distribution and vibration resistance from the integrated flange, preventing loosening under stress.
- Secure, high-torque fastening enabled by the external hex drive and coarse UNC thread, ensuring a reliable, tight fit.
- Maximum grip and holding power with a fully threaded 1/2" length, providing consistent performance across the entire fastener.
- Broad material compatibility for use in aluminum, brass, cast iron, and sheet metal, offering versatile application solutions.
- Guaranteed reliability and interchangeability through compliance with ASME B18.6.3 and RoHS 3 standards.
Professional Applications & Engineering Value
This 3/8"-16 UNC zinc-plated steel flanged tapping screw is engineered to solve critical challenges in metalworking and assembly. Its thread-cutting (Type F) design and coarse UNC thread create precise, strong threads in ductile materials like aluminum, brass, and cast iron, eliminating the need for pre-tapped holes and speeding up production. The zinc-plated finish provides a durable barrier against corrosion, essential for outdoor or humid environments. Combined with an external hex drive for high torque application and a flanged head that distributes clamp load and resists vibration, this screw ensures long-term joint integrity in sheet metal fabrication, machinery, and heavy-duty equipment, reducing maintenance and failure risks.
Specification Summary & Compliance
This screw features a 3/8"-16 UNC coarse thread with a diameter of 0.375" and a length of 1/2", designed as a fully threaded, thread-cutting (Type F) tapping screw with a blunt tip. It meets the dimensional and performance requirements of ASME B18.6.3 (SAE J933) and is RoHS 3 (2015/863/EU) Compliant, ensuring environmental safety and consistent quality for industrial use.
