Properties Of Self Clinching Nuts


Self Clinching Nuts are mostly found in machinery, electrical appliances and buildings, etc. The general raw material is metal or plastic, in a cylindrical shape, and the surface is engraved with high and low grooves called threads. The thread is a spiral inclined surface coiled around the side of the rivet nut, so that the rivet nut can use the screw mechanism to close the rivet nut cap or other objects. The inner side of these objects has threads corresponding to the rivet nut, called internal thread. Generally, the internal Rivet Nuts of rivet nuts or other objects need to be processed separately, but there is a kind of rivet nuts called self-tapping rivet nuts, which can cut internal threads on soft objects, so no extra processing is required. processing. 


The main function of the rivet nut is to join two objects, or to fix the position of an object. Rivet nuts can generally be removed or re-tightened at will without compromising their efficiency, provide greater strength than nails, and can be reused.

Generally, the diameter of the top of the rivet nut is relatively large, and the most common ones are round, square or regular hexagonal, and there are also flare-in nuts. If the top is a regular hexagon, you can use a wrench to turn the rivet nut. If the top is round, there will be grooves on the front of the top, so you can use the corresponding rivet nut driver to turn the rivet nut. The common grooves are one-shaped, cross-shaped and square, and there are other shapes. The more prominent top also prevents the multi-station rivet nut from drilling too deep and passing through the material, and improves the pressure of the rivet nut on the material. Some rivet nuts do not have a larger diameter top, such as fixed rivet nuts, so the rivet nuts can be completely locked into the workpiece without any exposed parts.

The thread of most rivet nuts has a certain direction, and the rivet nut can be locked when it is rotated clockwise. This kind of rivet nut is called a right-handed rivet nut. The left-handed rivet nut, which is opposite to the above-mentioned rivet nut, is only used under specific circumstances. Some rivet nuts will be subjected to counterclockwise torque when using the lower rivet nut, and the rivet nut will be loosened due to the torque received by the right-hand rivet nut. At this time, it is necessary to use a left-hand rivet nut, such as the left pedal of a bicycle. Left-handed rivet nuts will be used. However, the wheels on the left and right sides of the car are tightened with the rivet nuts on the right side, and there is no data showing that the looseness of the wheels is directly related to the thread of the rivet nuts.
