Problems solved by technology
[0005] Because the automobile adopts the electric circuit to work, therefore, the insulation of the installation of the bolt has great requirements. However, the bolts disclosed in the prior art mostly adopt an insulating sleeve on the bolt in order to realize the insulation. During the threaded connection process, The insulating sleeve is easy to be damaged, which will lead to poor insulation effect, easily cause circuit failure, and cause safety hazards
[0006] The essential reason causing the above-mentioned technical defects is: the bolts disclosed in the prior art fail to insulate in essence.

Embodiment Construction
[0043] The embodiments of the present invention are described in detail below. This embodiment is implemented on the premise of the technical solution of the present invention, and detailed implementation methods and specific operating procedures are provided, but the protection scope of the present invention is not limited to the following implementation example.
[0044] Such as Figure 1-8 As shown, a fastening bolt with good insulation performance for automobiles includes a bolt head, and the bolt head includes a polygonal bolt head 1, and the polygonal bolt head 1 is sleeved with a polygonal bolt head cap 4. The polygonal bolt head cap 4 is provided with an installation groove 41, and the polygonal body bolt head cap 4 is limited in the installation groove 41, and the polygonal body bolt head cap 4 is assembled on the polygonal body bolt by several fastening bolts 5. Head 1 on. There is a hexagonal groove on the fastening bolt 5, which is convenient for the wrench to tu...

Description
technical field [0001] The invention relates to a fastening bolt for automobiles, in particular to a fastening bolt with good insulation performance for automobiles. Background technique [0002] Fastening bolts are relatively important installation parts in mechanical connection parts. They are divided into ordinary and hinged holes according to the force of the connection. According to the shape of the head: there are hexagonal head, round head, square head, countersunk head and so on. Among them, the hexagonal head is the most commonly used. Generally, the countersunk head is used to have a matching countersunk groove where the connection is required. [0003] At the same time, fastening bolts are divided into two types: coarse thread and fine thread according to the tooth type of the thread, and the coarse tooth type is not displayed in the logo of the bolt. Bolts can be divided into low-carbon alloy steel or medium-carbon steel and heat-treated bolts according to the...
