SCREW, SCREW FOR MOUNTING BUILDING MEMBERS, AND MOUNTING STRUCTURE OF BUILDING MEMBER

摘要

PROBLEM TO BE SOLVED: To provide a screw capable of dispensing with drilling of a prepared hole in advance to save time and labor for construction work and being easily screwed in. SOLUTION: This screw has a shaft part 2 having a screw part 1 and a drill part 3 provided at a tip of the shaft part 2, and the screw part 1 is formed in only a part of the shaft part 2. This screw can be screwed in while drilling a hole by the drill part 3 provided at the tip of the shaft part 2. By forming the screw part 1 in only a part of the shaft part 2, friction caused by the screw part 1 when screwing in can be reduced when compared with a case where the screw part 1 is formed over the whole length of the shaft part 2.
