[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0030] like Figures 1-4As shown, a high-strength automotive bolt assembly in this embodiment includes a bolt body 3, which includes a screw 302 and a rotating head 301. The rotating head 301 has a hexagonal structure and is mounted on the top of the screw 302. An anti-torsion component 1 is provided at the connection between the top of the screw 302 and the rotating head 301. The anti-torsion component 1 includes an anti-torsion washer 101 and an anti-torsion washer 102. The anti-torsion washer 101 is mounted on the bottom of the rotating head 301, and the anti-torsion washer 102 is attached to the anti-torsion washer 101. The bottom of the anti-torsion washer 102 has its own... Adhesive layer; a locking nut 2 is installed at the bottom end of the screw 302. An anti-torsion component 4 is installed between the locking nut 2 and the screw 302. The anti-torsion component 4 includes a square plug 401 and a square slot 402. The square slot 402 is located in the middle of the bottom end of the screw 302, and the square plug 401 is installed in the middle of the locking nut 2. A limiting component 5 is also installed at the bottom end of the square plug 401. The limiting component 5 includes a screw head 502 and a cross nut 501. The screw head 502 is connected to the bottom end of the square plug 401, and the cross nut 501 is installed on the screw head 502. At the bottom, when the locking nut 2 is screwed onto the screw 302, the Phillips head 501 is at the bottom of the screw head 502. Rotating the locking nut 2 allows the screw head 502 to easily rotate relative to the locking nut 2, as the square plug 401 slides into the square slot 402. After the locking nut 2 is tightened, the Phillips head 501 is tightened onto the screw head 502, ensuring close contact between the upper side of the Phillips head 501 and the bottom of the locking nut 2. This effectively limits the position of the Phillips head 502 relative to the locking nut 2, thus cooperating with the square plug 401 to... A square slot 402 is used to prevent the locking nut 2 from loosening relative to the screw 302. The anti-torsion washer 101 is bonded to the rotating head 301. The contact surfaces of the anti-torsion washer 101 and the anti-torsion washer 102 are frosted. The frosted structure design ensures that the anti-torsion washer 101 and the anti-torsion washer 102 have sufficient frictional anti-torsion force when in contact, so as to prevent the high-strength automotive bolt assembly from twisting relative to the mounting screw hole of the automotive parts when the car is bumpy, and to prevent wear of the screw 302 and the threads at the mounting hole of the automotive parts.

[0031] like Figures 1-4As shown, in this embodiment, the top of the screw head 502 is welded to the square plug 401. The screw head 502 passes through the locking nut 2 and is rotatably connected to the locking nut 2. The welding fixation method can ensure the reliable fixation of the screw head 502 on the square plug 401. The rotatable connection ensures that the square plug 401 can easily rotate relative to the locking nut 2 under the action of the screw head 502 when the locking nut 2 is screwed onto the screw rod 302. The threaded part on the screw head 502 is located outside the locking nut 2. The cross nut 501 is screwed onto the threaded part of the screw head 502. The square plug 401 is slidably engaged with the square slot 402. The locking nut 2 is screwed onto the screw rod 302. The sliding engagement installation method makes the sliding of the square plug 401 into the square slot 402 more convenient and efficient.

[0032] like Figures 1-4 As shown, in this embodiment, the screw 302 and the rotating head 301 are an integral mechanism. The bottom end of the rotating head 301 is a disc-shaped structure. When the rotating head 301 is rotated, the screw 302 can be screwed into the mounting screw hole on the automotive parts to ensure convenient installation of the bolt body 3 on the automotive parts. The anti-torsion washer 101 and the anti-torsion washer 202 are both annular iron sheets. The annular iron sheet material of the anti-torsion washer 101 and the anti-torsion washer 202 can ensure that the anti-torsion component 1 has a certain structural strength and avoid easy deformation and damage.

[0033] The specific implementation process of this embodiment is as follows: First, the anti-torsion washer 101 is glued to the lower side of the turn head 301, and the anti-torsion washer 102 is glued to the mounting part on the automotive component, with the anti-torsion washer 102 facing the installed anti-torsion washer 101. Then, using the turn head 301, the screw 302 is screwed into the mounting screw hole on the automotive component, ensuring a tight fit between the anti-torsion washer 101 and the anti-torsion washer 102. Next, the Phillips head nut 501 is screwed to the bottom of the screw head 502, and the locking nut 2 is screwed into the locking end of the screw 302. As the locking nut 2 is tightened, the square plug 401 slides into the square slot 402, while the locking nut 2... After tightening the screw 302, tighten the Phillips head 501 onto the screw head 502 to complete the installation of the high-strength bolt assembly. Because this high-strength automotive bolt assembly effectively prevents relative torsion between the screw 302 and the mounting hole on the automotive part under the action of anti-torsion component 1, and effectively prevents relative torsion between the locking nut 2 and the screw 302 under the action of anti-torsion component 4, it not only effectively prevents wear on the external threads of the screw 302 and the threads at the mounting hole of the automotive part, but also avoids the safety hazard of loosening and falling off the high-strength automotive bolt assembly during use, thus ensuring the connection strength of the high-strength automotive bolt assembly.

[0034] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
