ABSTRACT:
A socket wrench with an ejector for severed collars of frangible fasteners has a conventional box ratchet wrench with a socket sleeve distally carried on the wrench body. The sleeve has a through aperture having internal flats and an internal lip at one end. The ejector member has an external diameter closely conforming to the internal diameter of the sleeve and slidably received therein. The cylindrical ejector has an annular shoulder intermediate its length and a ring permanently secured to its opposite end, with the sleeve lip captured between the ejector shoulder and ring. As the ejector is slidably mounted in the sleeve, it can be depressed into the socket, ejecting the threaded collar of the frangible fastener.
