Service HotlineA pin and a pin piece inserted on the pin, the width of the pin piece gradually decreases from the insertion end to the other end, and the pin piece is also provided with a protrusion, the protrusion is a triangular ratchet tooth shape, the An insertion hole is arranged on the pin, and a pawl corresponding to the protrusion is arranged in the insertion hole.
The hexagonal flange surface nut mainly includes a nut body, a flange surface is fixed at one end of the nut body, and a cap is fixed at the other end of the nut body. Has good sealing and corrosion resistance. The hexagonal flange surface nut mainly includes a nut body, a flange surface is fixed at one end of the nut body, and a cap is fixed at the other end of the nut body; since the cap is set on the nut body, it has the Better sealing can effectively prevent rain, moisture, dust and other harmful substances from immersing in the nut body, prevent the nut body from rusting, and greatly extend the service life of the hexagonal flange nut.

As a special kind of rivet parts, the rivets for shrinking brake pads are used in the accessories of the automobile industry. The original brake pad rivets do not have a chamfered structure, so the materials cannot be normally fed during assembly, or there are burrs, which lead to unqualified batches. When improving this structure, many manufacturers in the same industry often solve the problem by machining chamfering, but for brake pad rivets with thin thickness, it is impossible to achieve the problem of beating and bad material after chamfering processing.
In the installation of the external electrical components of the high-voltage electrical box, generally, the whole aluminum alloy profile with a T-slot is laid on the shell of the high-voltage electrical box, and then the upper nut is placed in the T-slot, and the bottom of the square nut is provided with a spring , When installing the electrical components, align the mounting holes with the screw holes of the square nut, then screw and tighten the screws to achieve the installation of electrical components. The biggest defect in the above installation process is that the alignment of the mounting hole and the screw hole is not very convenient, and the spring at the bottom of the square nut is easy to be missing. Once the spring is missing or damaged, the square nut cannot be effectively positioned in the T-slot. It makes the alignment of the mounting hole and the screw hole more difficult. Third, the above-mentioned connection and fixing method itself is not particularly ideal.
