5/8 Aluminum Hex Tube 72in Unthreaded

The ALLSTAR PERFORMANCE 5/8 Aluminum Hex Tube 72in Unthreaded is a precision-engineered structural component ideal for custom frame fabrication, roll cage construction, and suspension component assembly in performance and off-road vehicles. This hex tube is built to exacting standards, making it a trusted choice for fabricators and mechanics nationwide.

Constructed from lightweight aluminum alloy, the 5/8-inch hex profile provides superior strength-to-weight advantages over solid rod stock while maintaining excellent bending and torsional rigidity. The unthreaded design eliminates potential stress concentrations from threading, making it ideal for welded applications where full-penetration welds form the primary structural joint.

At 72 inches in length, the tube is ready for immediate fabrication—cut to your specifications, bent to precise angles, or welded directly into assemblies without preprocessing. Fabricators and custom builders rely on this tube for frame reinforcement and custom suspension links, ensuring dimensional stability and repeatable geometry in their projects.
