Great for making your own linkages or suspension components. Weldable tube ends are made from high strength 4130 chrome moly alloy steel and are available with Left Hand or Right Hand threads. Pieces with Left hand threads are identified with a machined groove. We suggest that these Tube Ends be welded in place by a skilled welder. Unlike other weldable tube ends that we stock, the 10-32 version is designed to fit over a 3/8" tube or rod.
