Abstract

PROBLEM TO BE SOLVED: To enable use of an open end wrench, a box end wrench, or a screwdriver other than an inch/milli hexagon end wrench by arranging a predetermined shape groove on the upper face of a head part of a hexagon socket head cap screw after the head part is machined into a predetermined shape. SOLUTION: After a head part of a hexagon socket head cap screw is machined into a hexagon head 2, a groove is arranged on an upper face 3 of the hexagon head 2. In usage, a hexagon end wrench is inserted into the hexagon socket for attaching/detaching the bolt. If the hexagon socket is crushed and use of the hexagon end wrench is refused, an open end wrench or a box end wrench is used in the hexagon head 2 so that the bolt can be attached/ detached. If the angles of the hexagon head 2 are crushed and use of the open end wrench or the box end wrench becomes impossible, a screwdriver is used in the groove on the upper face 3 in the hexagon head 2 so as to attach/detach the bolt. Alternatively, a screwdriver with a cross-headed tip can be also used when one more groove is arranged diagonally to the groove on the upper face 3 in the hexagon head 2.

A groove is provided in the hexagonal head of (2) to form (3). The present invention has the above configuration. When using the present invention, bolts can be attached and detached as follows. (1) Insert a hexagon wrench into the hexagon hole (1) and attach it.
Remove it. (2) In (1), when the hexagonal hole is crushed and the hexagonal wrench cannot be used, the bolt head (2) can be used to attach and remove it using a spanner or a wrench. (3) At (2), the corner of the bolt head (2) is crushed,
If you can no longer use a spanner or an open-end wrench, you can attach and remove it using a slotted screwdriver in the groove of the bolt head (3). In addition, another groove is set at the diagonal of (3).
You can also use a Phillips screwdriver by putting it in.
