ABSTRACT:
A screw or nail sustainer comprising a tube having a chamber for inserting a screw or nail into a base opening of the chamber, at least one fluid flow opening formed with a base portion of the tube for injecting a liquid resin, and at least one ring-like projection formed with a portion of the tube remote from the fluid flow opening toward a tip of the tube to project from and to surround a periphery of the tube. A plurality of bag forming wings are provided with the tip portion of the tube to project radially. The bag forming wings are bent toward the base portion of the tube when the screw or nail sustainer is inserted into a hole of a board so that a bag like portion may be made in cooperation with the outer surface of the tube so as to make an opening toward the base portion of the tube.
