That is, the friction protrusion (210) is formed with a material having a hardness lower than that of the head (1), so that when the tool does not match, it is more likely to be broken and deformed due to the tool, thereby expanding to the gap with the tool to prevent the tool from wandering.

The method of use and the effect of the bolt (10) having a friction portion according to an embodiment including the above constituent elements will be described below.

The tool is combined with the combination groove (100) of the head (1), and the threaded part (2) can be rotated by means of the tool and fastened to the structure.

At this time, the tool is combined with the combination groove (100), and when it is in a mismatched state with the combination groove (100), it will stick to the friction protrusion (210), so that it can be in a state of not moving and not breaking away from the combination groove (100) down to rotate the head (1).

At this time, the friction protrusion (210) provides friction to the tool, thereby preventing the tool from wandering or disengaging. The tool is broken and expanded to the gap between the tool and the coupling groove (100), preventing the tool from wandering or dislodging from the coupling groove. (100) Detachment.

As above, according to an embodiment of the bolt (10) with a friction part, the friction protrusion (210) constituting the friction part (200) protrudes at the entrance part (110) or the accommodation part (120) constituting the coupling groove (100). Even when the tool is not matched, it will stick to the tool and provide friction, thus preventing the tool from shaking or falling off.
