ABSTRACT:
A hold out spring is provided on a threaded bolt. The bolt is adapted to be inserted through a hole in a panel. The hold out spring is inserted into a bore in the bolt, riding in spaced diametrically opposed internal grooves therein, the hold out spring extending out of a slot in the bolt. A washer having inwardly extending tabs is now installed on the shank of the bolt, the tabs riding in grooves extending along the outer body of the bolt and stopped in their downward movement by engagement with a stop ring mounted in a groove adjacent the nose of the bolt.
