Dome Nut Customized Hexagon Decorative Nut Wheel Screw Decorative Nut M4 M5

As is well known, screws and nuts are widely used as connectors in various mechanical equipment, making them easy to disassemble. However, for equipment whose internal structure needs to be kept confidential, they generally do not need to be disassembled after assembly. As screws and nuts can be easily disassembled, equipment that needs to keep its internal structure confidential cannot be kept confidential.

(4) The matching requirements for motor components, gears, and screw components are high. It is necessary to ensure that the three axes are parallel and on the same plane. A slight deviation in parallelism and flatness can affect the meshing requirements, resulting in high tool noise. [8] 7. In terms of appearance design, the arrangement of various accessories is limited by parallel arrangement. For example, the motor must be placed in the parallel direction of the screw direction, which greatly limits the use of space, resulting in a lot of space waste. The tool appearance is bulky, and the handheld center of gravity cannot meet the needs of human mechanics. The handshake handheld port does not have a good point of force, making it easy to fatigue during use. The existing conditions are difficult to change this inhumane mechanism layout.

The existing wooden screws are composed of a threaded part with a conical angle and arranged along the conical rod, and a screw head. The head of the screw can be countersunk, hemispherical, or other shapes, and the screw head has grooves that fit with the tool, including a straight groove and an inner concave cross groove. The cone angle of existing wood screws can be either 45 degrees or 60 degrees, and the front end of the cone angle is a pointed end formed by rotating threads. There are three shortcomings in the use of existing wood screws, as their cone angle is 45 degrees or 60 degrees, and the thread profile angle is all 60 degrees, which makes it difficult to enter the material with high resistance. Therefore, it is difficult to manually screw in existing wood screws, especially when used in hard wood materials, and it often occurs that the screw head groove is damaged; When attacking wooden materials, due to the fact that the screw tip is composed of rotating threads, a large lateral torque is formed during rotation, which is prone to deviation from the center position; In addition, due to the conical shape of existing screws, they will be subjected to both radial and axial forces when entering the material, resulting in a complex stress state. Therefore, it is easy to cause expansion and cracking of the penetrated wooden material, and even longitudinal cracking of the material, making it unusable.

How to use, what is Rivet nut? Usually, when installing various parts in cars or individual boards in aviation, rivet nuts used inside elevators are used to install certain screws. The commonly used parts are very important connecting parts, so the selection of rivet and nut materials is very important. What is the method of using rivet nuts? Let's watch together. Rivet nuts are used in the fixed field of various metal plate, pipeline and other manufacturing industries, and are widely used for the assembly of electromechanical and light industrial products such as automobiles, aviation, railways, refrigeration, elevators, switches, instruments, furniture, decoration, etc. Designed to solve the shortcomings of sheet metal, thin-walled pipe welding nuts, substrate welding deformation, internal thread taper, etc., without the need for internal threads, welding nuts, rivets, efficiency, and convenient use.
