A rod having rolled threads is threaded into a tapered boss on a clevis and a jam nut on the rod has a tapered skirt frictionally embracing the tapered boss to securely lock the nut. Extruded bearing openings in the legs of the clevis provide enlarged bearing surfaces. The boss threads are formed in a clevis blank having a boss opening of substantially the same diameter as the unthreaded rod and the other end of the rod is in the opening of a substantially identical clevis blank and is welded thereto. |
