Detailed Description
The preferred embodiments of the present invention will be described in conjunction with the accompanying drawings, and it will be understood that they are presented herein only to illustrate and explain the present invention, and not to limit the present invention.
Example (b): as shown in fig. 1, the utility model relates to a high strength screw for car, including screw rod 1, screwhead 2, first nut 3, second nut 4 and spacing 5, screwhead 2 sets up in the one end of screw rod 1, and first nut 3 and second nut 4 all overlap and locate on screw rod 1. As shown in fig. 2, the screw 1 is provided with the reinforcing external thread 6 and the common external thread 7, and the crest of the reinforcing external thread 6 is wider than the crest of the common external thread 7, so that the strength is higher, and the thread deformation can be prevented, thereby causing the thread slipping of the first nut 3. The other end of the screw rod 1 is provided with a pointed part 8, the middle part of the screw rod 1 is provided with a first limiting groove 9, and the limiting strip 5 is arranged in the first limiting groove 9.
