* 도면의 주요부분에 대한 부호의 설명* Explanation of symbols for main parts of the drawings

1 : 나사못 2 : 머리부1 screw 2 head

3 : 나선 4 : 나선홈3: spiral 4: spiral groove

본 고안은 머리부에 수개의 나선홈을 형성하여 나사못 삽입시 머리가 돌출되지 않도록 한 나사못에 관한 것이다.The present invention relates to a screw that forms a number of spiral grooves in the head so that the head does not protrude when the screw is inserted.

종래의 나사못은 단순히 몸체에만 나선이 형성된 것이었기 때문에 나사못을 삽입하면 나사못의 머리까지 완전히 삽입되지 못하고 약간 외부로 돌출하는 경우가 많아 사용상으로나 외관사으로나 좋지 않은 결점이 있는 것이 었다.Since the conventional screw simply formed a spiral only in the body, when the screw is inserted, the screw is not completely inserted up to the head of the screw and often protrudes outwards, which is a disadvantage in terms of use and appearance.

본 고안은 이러한 결점을 시정하기 위하여 안출한 것으로서 이를 첨부도면에 따라 상세히 설명하면 다음과 같다.The present invention has been devised to correct these defects, and described in detail according to the accompanying drawings as follows.

나사못(1)의 머리부(2)에 측면과 저면에 걸쳐 몸체의 나선(3)과 같은 방향으로 회전하는 수개의 나선홈(4)을 형성하여서 된 것이다.The head 2 of the screw 1 is formed by forming several spiral grooves 4 that rotate in the same direction as the spiral 3 of the body over the side and bottom.

미 설명 부호(5)는 피삽입물이다.Reference numeral 5 is an insert.

이와같이 구성된 본 고안은 나사못(1)삽입시 몸체에 형성된 나선(3)에 의하여 나사못(1)이 삽입되는 것은 종래와 같으나 나사못(1)이 삽입되고 머리부(2)의 저면이 피삽입물(5)에 접하게되면 머리부(2)의 저면과 측면에 걸쳐 나선(3)방향으로 형성되 수개의 나선홈(4)에 의하여 나사못(1)의 머리부(2)까지 피삽입물(5)에 쉽게 삽입되므로 머리부(2)가 돌출되지 않고 깨끗이 함몰되어 외관상 보기가 좋을뿐 아니라 사용상 걸리적 거리지 않는 작용효과가 있는 것이다.The present invention configured as described above is a screw (1) is inserted into the screw (1) by the spiral (3) formed in the body when the screw (1) is inserted, but the screw (1) is inserted and the bottom surface of the head (2) to be inserted (5) When it comes into contact with the head), it is formed in the direction of the spiral (3) across the bottom and side of the head (2) is easily inserted into the insert (5) to the head (2) of the screw (1) by a few spiral grooves (4) Therefore, the head (2) is not protruded cleanly depressed not only looks good but also has a working effect does not interfere in use.
