S-90096A354 3/8"-16 x 3" ASME B18.6.3, SAE J933 Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction, ensuring long-lasting performance in harsh industrial environments.
• High-torque installation capability thanks to the external hex drive design, allowing for secure fastening with standard tools.
• Efficient thread cutting action that creates strong, reliable threads in materials like aluminum, brass, cast iron, and sheet metal without pre-tapping.
• Enhanced load distribution from the integrated 0.78" flange, reducing surface pressure and preventing material damage.
• Full threading for maximum grip along the entire 3" length, providing consistent holding power in deep applications.
• Wide material compatibility with coarse UNC threads designed for use in both soft and hard metals, streamlining inventory.
• Flanged design eliminates need for separate washers, speeding up assembly and reducing component count.

Professional Applications & Engineering Value

Engineered for demanding industrial fastening, this 3/8"-16 UNC tapping screw delivers reliable performance in aluminum, brass, cast iron, and sheet metal applications. The zinc-plated steel material offers excellent corrosion protection, while the thread cutting design ensures secure, vibration-resistant connections without pre-drilled threads. The external hex drive allows for high-torque installation, making it ideal for assembly lines and heavy machinery where speed and strength are critical. Its flanged head distributes clamp load evenly, preventing pull-through in thin materials and reducing the risk of joint failure under dynamic loads.
