PURPOSE: To improve retainability and fittability to a support by combining a second fastener made of a resin having a member mounting head and a notch with a fastener made of a resin having a head abutting against the support, a tapping threaded portion of an outer wall and a snap enagement device. CONSTITUTION: A tapping threaded portion 5 is provided on the outer surface of a body 4 of a resin-made fastener 1 having a nipple 3 and a body 4 at the other end of a flange 2 abutting against a support, the inner peripheral wall section of the portion is hexagonal, and a circular bead 8 is projected on the side of a small-diameter portion. A large-diameter body 15, a cylindrical portion 14, notches 13A-13D and a cross-section conical end portion are sequentially formed from a head 10 having a device for installing a member to be fixed to construct a second fastener 9, and both fasteners 1, 9 are formed of a resin to be combined for use. Accordingly, the retaining force to the support can be secured and installation can be accomplished easily and inexpensively. |
