WIRE GRIP HOSE CLAMP Abstract of the Disclosure A wire grip hose clamp is disclosed, adapted to be applied to a hose by a driving tool having a rotatable socket. The clamp is characterized by having incorporated therein a screw having a relatively long head which is received in said socket, and a base flange formed integrally with said head and of enlarged diameter whereby to provide additional bearing surface for the end of the socket. The base flange has a conical or chamfered surface. These improvements are designed to prevent or minimize any tendency of the socket to become disengaged from the screw during installation of the clamp on the hose. The screw, including the head and flange, are made by forging or cold heading. Background of the Invention This invention relates, as indicated, to wire grip hose clamps. Wire grip hose clamps have heretofore been manufactured, in which a slotted screw is employed for closing or tightening the clamp, such screw having a relatively short hex head having a thin circular base flange or washer of relatively small diameter. The clamp is usually made of a single piece or length of wire, bent or formed to provide circular hose-gripping portions which terminate in free ends or tails which lie
