• Quick Installation with Standard Tools: External hex drive head allows for high-torque application using common wrenches, speeding up assembly processes.
• Versatile Material Compatibility: Specifically designed for use in aluminum, brass, cast iron, and sheet metal, offering reliable fastening across multiple applications.
• Full Thread Engagement: Fully threaded design maximizes holding power and ensures consistent performance along the entire screw length.
• Regulatory Compliance & Quality Assurance: Meets ASME B18.6.3 and SAE J933 standards, with RoHS 3 compliance for safe, eco-friendly use in global markets.

Professional Applications & Engineering Value

Engineered for demanding industrial settings, this 3/8"-16 UNC flanged hex tapping screw delivers exceptional value by solving common threading challenges in metals. The zinc-plated steel material provides a protective barrier against rust and corrosion, extending service life in outdoor or humid conditions. Its thread-cutting design eliminates the need for separate tapping operations, reducing labor time and costs when fastening into aluminum, brass, cast iron, or sheet metal. The external hex drive and flange work together to prevent cam-out and maintain clamp force, crucial for assemblies subject to vibration. Ideal for machinery, automotive, and metal fabrication, this screw ensures reliable, repeatable performance while adhering to strict ASME B18.6.3 specifications.
