Bolts are widely used as common fasteners. The traditional T-bolt consists of a head, a screw and a tail. The head is a long plane. During the use of the T-bolt of this structure, the T-bolt and the groove The contact surface of the track is a smooth surface, its friction force is not large, its connection is not firm enough, and it is easy to fall off. For this reason, some people design the head as a bevel to increase friction, but only one bevel is in contact with the part in this design, and the sealing is not very good

At present, machinery and equipment have gradually become the main force of work production. Many equipment require frequent maintenance and even replacement of parts during use. During the process of maintenance and replacement, it is inevitable to encounter the problem of screw disassembly and assembly. In the process of disassembly and assembly, it is almost necessary to cooperate with both hands, or because the thread is too long, installation and disassembly are very cumbersome. Especially in the butt installation of flanges, bolts and nuts are used for clamping and fixing at this stage. During use, two hands are required to hold a board, a fixed screw, and a screw nut. This is to prevent the nut from During the turning process, the screw also rotates. When screwing, the wrench should be taken down without interruption, re-selected a good position, and then screw the screw forcefully again, and repeated several times before the screw can be unscrewed. Time and labor costs for maintenance are wasted. At present, there is no screw that is easy to install and remove.

In the prior art, the hardware and the handle are generally assembled and connected by means of rivet riveting; in the process of assembling the hardware and the handle, the prior art adopts manual operation to realize the riveting and assembling process, which is time-consuming and labor-intensive. and low productivity.

The locking effect of the spring washer is general, and the important parts are used as little or not as possible, and the self-locking structure is adopted. For spring washers used for high-speed tightening (pneumatic or electric), it is best to use surface phosphating washers to improve their anti-wear performance, otherwise it is easy to burn out or open mouth due to friction and heat, and even damage the surface of the connected parts. For thin plate joints, spring washer construction should not be used. According to statistics, spring washers are used less and less in automobiles.

We have many years of experience in the production and sales of screws, nuts, flat washers, etc. The main products are: lifting mother hardware rigging rings, countersunk head machine screws, flat head full hexagonal blind hole rivet nuts, main board circuit board support and isolation copper column nuts and other products , we can provide you with a fastener solution that suits you.
