This “Square Adapter” is designed to adapt a spherical rod end, bushing or any 5/8-18 male threaded hardware in to a fabricated component with flat sides. The adapter measures 1″ X 1″ X 1-1/2″ long. It may be welded onto any flat surface or 90-degree corner. It can also be inserted into the end of a 1-1/4 X 1-1/4 X .120 wall square tube, after grinding the corners of the adapter to round them over slightly. At CSD Racing Products, we use them for our custom RZR 170 Fabricated Trailing Arms. But you can probably think of dozens of uses for them.
