A screw grommet with which an externally threaded member is threadedly engaged in a state in which the screw grommet is inserted through an attaching hole formed in a member to which the screw grommet is to be attached. An externally threaded member is passed through a head having a through hole, and the head abuts against the member to which the screw grommet is to be attached. The externally threaded member is then inserted through a leg which projects from the head and is inserted through the member to which the screw grommet is to be attached. The externally threaded member is threadedly engaged with an internal thread member. A pair of pawls are formed on a part of the internal thread member and are, together with the internal thread member, inserted in the leg in a state in which the diameter of the pawls is reduced. When the internal thread member approaches the head, the diameter of the pawls is enlarged in such a manner as to clamp the member to which the screw grommet is to be attached. When the internal thread member is moved away from the head, the diameter of the pawls is reduced so as to allow passage of the pawls through the attaching hole formed in the member to which the screw grommet is to be attached. The pawls hold the internal thread member in such a manner as to prevent the internal thread member from falling from the leg.
