NAIL WITH BOLT AND WOOD SCREW WITH BOLT

摘要

PURPOSE: To facilitate positioning or demounting/assembling of members so as to improve workability by integrating a bolt shaft part with the head part of a nail or a wood screw. ;CONSTITUTION: A bolt 2 is integrated with one end of a nail 1 or a wood screw 5. One side of the nail 1 part or the wood screw 5 part is fixed by driving or screwing, however, the other side of the bolt 2 part allows any part to be fixed by a nut. The nail with bolt or the wood screw with bolt is held by one hand and driven or screwed into a base board by means of a hammer, a driver, spanner, or the like. A perforated upper board is attached and fixed by a nut. As a result, a nail or a wood screw which is conventionally left on an upper plate side at demounting is left on a base board side so as to elucidate reproductivity of location and also improve workability. It is desirable that a driven part or a spanner hook part is formed at the end of the bolt as necessary and a detent such as a projecting part or a streak is added below the neck of the nail part.;COPYRIGHT: (C)1994,JPO&Japio
