Weld-In Stub for .120 3/4in Tubing

The Weld-In Stub for .120 3/4in Tubing is a precision fabrication component designed for custom frame and structural builds in tactical equipment manufacturing. This component serves as a critical junction point for welded assemblies, allowing integrators and gunsmiths to extend or modify tubing runs with a permanent, load-bearing connection.

Manufactured by Woodward Machine under part number ST201A, this weld-in stub is specifically designed to mate with .120-wall 3/4-inch tubing, ensuring dimensional consistency and structural integrity in finished assemblies. The stub's length of 2.95 inches provides adequate surface area for full-penetration welds while remaining discreet in final installations. Weighing just 0.2 pounds, it adds minimal weight to your build, making it ideal for weight-conscious tactical platforms.

Serious builders—from law enforcement armors to competition shooters and custom equipment manufacturers—rely on Woodward Machine components for their dimensional accuracy and weldability. This stub is most commonly used in modular frame extensions, upper receiver adapters, and equipment mounts, ensuring reliable, repeatable welds that meet professional standards.
