S-90096A361 1/2"-13 x 1 1/2" ASME B18.6.3, SAE J933 Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction, extending service life in demanding industrial environments.
• Efficient installation and high clamping force provided by the integrated flange, eliminating the need for a separate washer.
• Excellent thread-cutting performance in tough materials like aluminum, brass, and cast iron, reducing installation torque and preventing stripping.
• Secure, high-torque driving with the external hex head design, ensuring reliable fastening in heavy-duty applications.
• Wide material compatibility for use in sheet metal, cast iron, and non-ferrous metals, offering versatile application solutions.
• Reliable coarse UNC thread for quicker assembly and reduced cross-threading risk in coarse-grained materials.
• Full threading for maximum grip along the entire shank, providing consistent holding power across the entire fastened length.

Professional Applications & Engineering Value

This 1/2"-13 zinc-plated steel flanged hex tapping screw is engineered to solve critical fastening challenges in industrial assembly. Its thread-cutting design (Type F) and coarse UNC thread enable it to form precise, strong threads directly in aluminum, brass, cast iron, and sheet metal, eliminating the need for pre-tapped holes and speeding up production. The zinc plating provides a protective barrier against rust and corrosion, essential for maintaining integrity in harsh conditions. The integrated flange distributes clamping force over a wider area, reducing material stress and preventing loosening under vibration. Combined with the external hex drive for high-torque application, this screw delivers reliable, durable performance for heavy-duty industrial fastening where precision and strength are non-negotiable.
