材が脆い材質の場合、共回りが顕著に発生する。[0006] Such a fastening method using a plug is
Since the tapping screw is screwed into the plug inserted in the pilot hole of the member to be screwed, there is no direct screwing portion of the tapping screw into the member to be screwed, and therefore,
When the tapping screw is initially screwed, the plug may rotate together, which may make fastening impossible. Particularly, when the member to be screwed is a brittle material, the co-rotation remarkably occurs.
【０００７】また、プラグの使用は、コスト的に割高と
なると共に、施工に手間がかかるという問題もある。Further, the use of the plug is not only costly but also troublesome in construction.

が得られることになる。The screw thread 13 of the tapping screw 11 bites into both the body portion 2 and the member a to be screwed in, and the screw thread 13 in which the body portion 2 is difficult to be held is flexibly clamped, so the idling of the tapping screw 11 occurs. When the pulling force after fixing is applied, the screw thread 13 into which the member to be screwed a is difficult is firmly fixed and exhibits momentary strength, and at the same time, the male screw in which the body part 2 is difficult to flex the pulling force. It can withstand vibration and long-term strength, and since the retaining portion 3 connected to the body portion 2 is located on the back side of the screwed member a, the reliable retaining state of the tapping screw 11 can be ensured. Will be obtained.
