があった。The conventional wood screw and tapping screw have a cross hole, a hexagonal head, etc., which are mounted on the head for fastening and fixing to the plate material or plywood of the member to be fastened. It is difficult to say that these configurations are suitable for pulling out after tightening.Therefore, it is difficult to use when the member to be fastened that needs to be removed from the plate material or plywood after concrete pouring and dismantled is a formwork. Had a point. However, in the formwork method, when constructing the weir,
In many cases, it is not possible to put together only standard size combinations, and here auxiliary plates with irregular dimensions (such as timbers and thick timbers)
In this case, there are many corners of the construction site where auxiliary plates are often used, and there is no space to swing the hammer. Although the plate is fixed, it is very troublesome to simply slip onto the conventional head and tightening work in a narrow space where wood screws with a cross hole etc. are recessed because the tightening tools can easily come off from the head. , It is particularly inconvenient to loosen and turn the wood screw once tightened, and when the head of the wood screw exists in a narrow and deep position, it is inconvenient to insert the tip of the tightening tool and search for the cross hole. The work of deframing the auxiliary plate while applying it was troublesome and troublesome.

It is an object of the present invention to provide a wood screw which can be made flat and can be folded so that the head does not protrude when the protrusion due to the height of the head after tightening is an obstacle.
