S-93882A228 10-24 x 3/8" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction, extending service life in demanding industrial environments.
• High-strength thread forming design creates durable, permanent threads in materials without pre-tapped holes, reducing assembly steps.
• Excellent material compatibility for use in steel, aluminum, brass, cast iron, and sheet metal, providing versatile application solutions.
• Secure, vibration-resistant fastening from the UNC coarse thread profile, maintaining clamp load under dynamic conditions.
• Quick and easy installation with external hex drive and flanged head, allowing for high-torque application and eliminating the need for a washer.
• Full threading for maximum grip length, ensuring a strong hold along the entire 3/8" shank in various material thicknesses.
• Streamlined procurement and installation with standard No. 19 drill bit size, simplifying the tooling requirement for production lines.

Professional Applications & Engineering Value

This 10-24 UNC thread forming tapping screw is engineered to solve common assembly challenges in metalworking and fabrication. Its zinc-plated steel body provides essential corrosion protection for longevity in industrial settings. The thread forming (SW) design is critical for creating strong, clean threads in ductile materials like steel, aluminum, brass, and cast iron, eliminating the risk of chip formation associated with thread cutting and ensuring a reliable, vibration-resistant joint. The combination of a coarse UNC thread and external hex drive facilitates rapid installation with common tools, reducing assembly time and labor costs. The integrated flange distributes clamping pressure over a wider area (0.414" diameter), making it an ideal sheet metal fastener that resists pull-through, thereby enhancing the structural integrity of the assembled product.

Specification Summary & Compliance

This screw conforms to Unified National Coarse (UNC) thread standards. The zinc-plated steel construction offers good corrosion resistance, and the product is supplied with a blunt tip and is fully threaded. It is designed for use with a standard No. 19 drill bit (0.165" diameter). Manufactured to industry standards for dimensional accuracy, this fastener is suitable for a wide range of industrial and construction applications.
