To provide a screw capable of efficiently performing work of fastening and fixing an article to be fixed with proper fastening torque, and performing adjusting work of screw fastening.SOLUTION: A screw is equipped with a screw portion 2 screwed in a substrate, a first part 4 that is provided on the opposite side of a tip end portion of the screw portion 2 with respect to the screw portion 2 and to which a first tool for fastening the screw portion 2 is attached, a collar portion 3 that is provided between the screw portion 2 and the first part 4, and is configured to have a larger diameter than that of the screw portion 2, a fragile portion 5 that is provided between the collar portion 3 and the first part 4 and is configured to be parted between the collar portion 3 and the fragile portion with fixed torque when fastening torque is applied to the first part 4, and a second part 6 that is integrally provided with the collar portion 3, is configured to maintain the integral state with the collar portion 3 even if the fragile portion 5 is parted, and to which a second tool for fastening the first tool or the screw portion is attached.SELECTED DRAWING: Figure 1
【課題】固定対象物を、適切な締付トルクで締め付け固定する作業を作業効率良く行うことを可能とするとともに、ネジ締付の調整作業を行うことを可能とするネジを提供する。【解決手段】下地に螺入するネジ部２と、ネジ部２に対してネジ部２の先端部とは反対側に設けられ、ネジ部２を締め込むための第一工具が取り付けられる第一部分４と、ネジ部２と第一部分４との間に設けられ、ネジ部２よりも大径に構成された鍔状部３と、鍔状部３と第一部分４との間に設けられ、第一部分４に締付トルクが付与された際に一定のトルクで鍔状部３との間で分断されるように構成された脆弱部５と、鍔状部３と一体的な状態で設けられ、脆弱部５が分断されても鍔状部３と一体的な状態を維持するように構成され、第一工具またはネジ部を締め込むための第二工具が取り付けられる第二部分６と、が備えられている。【選択図】図１
