摘要： Provided is a crimp securing structure of a bolt in which a crimp bolt 10 having a crimping recess 13 on the upper surface of the head is crimped onto a metal sheet 30. The thickness of a metal material press-fitted into the crimping recess 13 of the crimp bolt is made smaller at the peripheral edge of the crimping recess 13 and is made larger in the center portion thereof. In order to obtain this crimp securing structure, a crimping die 20 in which a stress-relief recess 23 is formed in a center portion of a convex portion is used to prevent the occurrence of excessive local stress in the crimping recess 13.

摘要： To reduce the load required to press-fit a nut into a plate material, the nut includes a base part 2 provided with a female screw 18, a cylindrical protrusion part 3 protruding from one surface of the base part and a plurality of foot parts 4 protruding from an outer peripheral surface side of the protrusion part. An end of the respective foot parts closer to the protrusion part is formed so that a width gradually expands from a tip end side toward a protrusion part side, and that both outer sides of the end are arc-shaped in plan view.

摘要： The bolt of the present invention can reliably peel coating even when fastened with a low torque, and can secure sufficient conductivity. A coating peeling part 4 for peeling coating is formed at a tip end of an axis part 2 in which a regular screw part 1 is formed. The coating peeling part 4 includes crushing parts 5 having a trapezoidal top part and having a flank which is projected at a different angle with respect to the flank of the regular screw part 1; and a protruding part 6 which is arranged adjacent to the crushing parts 5 and whose top part projects beyond the outer diameter of the regular screw part 1.

摘要： A piercing nut according to the present invention includes an internal thread 11, a ring-shaped punching part 12, a ring-shaped groove 16, and a bearing surface 17. The internal thread 11 is formed at the center of a nut main body 10. The ring-shaped punching part 12 protrudes around the outer periphery of the internal thread 11. The ring-shaped groove 16 is formed around the outer periphery of the ring-shaped punching part 12. The bearing surface 17 protrudes around the outer periphery of the ring-shaped groove 16. The height h of the ring-shaped punching part 12 is equal to or lower than the height H of the bearing surface 17 in the opposite manner to the conventional technique.

摘要： The present invention provides a bolt that can exhibit a looseness-prevention function even though the bolt is repeatedly attached and detached. A bolt 1 includes a groove 4 that extends along a helix of a screw thread 3 and that is provided on a peak 31 of the screw thread 3. Further, the bolt is configured to include a plurality of the grooves 4 being spaced apart from each other along a helical direction of the screw thread 3.
