摘要： PROBLEM TO BE SOLVED: To provide a projection welding nut made of aluminum alloy capable of securing both the bonding strength of a weld and the thread strength of a threaded part.
SOLUTION: The projection welding nut 10 made of aluminum alloy is formed from the threaded part 14 consisting of 7000 series aluminum alloy material and a projection part 16 consisting of a 5000 series or 2000 series aluminum alloy material. The former has a property with high thread strength, while the latter has a property with high resistance against separation. Accordingly this allows securing both the bonding strength of the weld and the thread strength of the threaded part.

摘要： PROBLEM TO BE SOLVED: To provide a screw part structure for a female screw and a male screw for achieving anti-loosening effect by combination of the female screw and the male screw.
SOLUTION: Of an inlet side end part and an outlet side end part of a screw part of the female screw, the outlet side end part is shrunk to be tapered along the whole circumference to have smaller inner diameter than a middle part to form the screw part, where threads of the female screw part with shrunk diameter are formed as irregularities repeatedly continuous in a circumferential direction. In trough bottoms of the screw part of the male screw to be engaged with the female screw, irregularities repeatedly continuous in a circumferential direction are formed. As the male screw is engaged with the female screw, at least one of projected parts in the threads of the female screw part with shrunk diameter is engaged with at least one of recesses in the trough bottoms of the male screw part of the male screw. The projected part of the female screw part with shrunk diameter bites the trough bottom of thread side surface of the male screw part to tighten them. Loosening between the male screw and the female screw can thus be prevented.

摘要： PROBLEM TO BE SOLVED: To provide a bolt which enables to screw by correcting an inclination, a position slippage, and the like, even though such an inclination, a position slippage, and the like are relatively generated, between the bolt and the female screw of a nut and the like to be the screwing object. SOLUTION: By making an elliptical loop (a loop line), in which a plane inclining to a plane which is orthogonal to the center line of a bolt, and the outer peripheral surface of a bolt, are crossed as a standard, a screwing-in correcting surface is formed at the screw-in side of the bolt almost along this loop. Then the outer diameter in the direction square to the center line of the bolt, at the outer brim of the screw-in correcting surface (shaft square outer diameter) is made larger than the valley diameter of the male screw of the bolt, and the male screw is formed from this screw-in correcting surface.
