Weld-In Stub for .065 3/4in Tubing

The Weld-In Stub for .065 3/4in Tubing (model ST201B) is a precision-engineered weld-on coupler component designed for custom steering and suspension fabrication work. Built by Woodward Machine—a trusted name in performance automotive engineering—this stub serves as the fixed half of a quick-release disconnect coupling system. It's an essential component for fabricators, hot rodders, and professional mechanics building custom steering columns, fuel system assemblies, or drive shafts where future disassembly or adjustment is critical to serviceability.

This stub features a 3/4-inch tubing interface with 0.065-inch wall thickness—a specification that balances structural rigidity with minimal weight for performance applications. The steel construction with natural finish allows for direct TIG or MIG welding into your custom frame, chassis, or component assembly without pre-machining. The 20-spline engagement pattern ensures repeatable, secure connections under load while accommodating quick disconnects without play or lateral movement. Weighing only 0.23 lbs, the compact 1.4 x 0.85 x 4-inch profile fits tight fabrication spaces typical in roll cage, suspension, and driveline modifications.

Fabricators working on universal steering conversions, shaft couplers, or removable fuel system assemblies will find this stub indispensable for permanent installation points. It pairs seamlessly with matching quick-release disconnects to create modular systems that can be serviced or reconfigured without cutting welds. Professional builders, restoration specialists, and off-road vehicle enthusiasts rely on Woodward Machine weld-in stubs for durability and precision fit. Installation requires basic welding skills and proper fixture alignment to ensure coupling surfaces are perpendicular and coaxial with the host structure.
