Abstract

PURPOSE: To make it impossible to recognize that there is a tool engaging member and to drive the screw out easily after the setting up by arranging the tool engaging member in the screw head and capping the screw head with a hiding member to hide the tool engaging member. CONSTITUTION: A screw body 1 having the shape of a bolt has a cylindrical screw head 3 at one end of a screw shaft 2. A hexagonal engaging recess 4 as a tool engaging member is arranged on the top surface of the screw head 3, and a male screw portion 5 is arranged on the periphery of the screw head 2. A hiding member C is mainly constituted by a hemi-spherical embedded member 6 and a hexagonal driving head 7, which are connected by a notch 9 capable of being cut off when applied by a turning force of about a predetermined torque. A hollow portion for accommodating the screw head 3 is arranged in the embedded member 6. A female screw portion 8 is arranged on the inner periphery of the hollow portion.
