Replaceable Fastener for Cover Plates And The Like Abstract The push frame of a tractor-scraper normally has a plurality of cover plates releasably secured therebelow to provide access internally of the push frame. In standard practice, the cover plates are secured to the push frame by a plurality of bolts and the heads of the bolts are subjected to wear and possible breaking-off due to their exposure upon opera- tion of the tractor-scraper. This invention provides a mounting assembly for expeditiously removing and replacing the cover plates upon wearing or breaking-off of the heads of bolts thereof by providing an intern- ally and externally threaded bushing which is thread- ably connected on the push frame and is further threadably connected to each bolt. Thus, a workman need only engage the bushing with a socket wrench or the like to release the bolt and thus the cover plate upon wearing or breakinq-off of the heads of the bolts.
