The size of flange nut and general hex nut is basically the same as the thread specification, but compared to hex nut, it is a one-piece gasket and nut, and there are anti-skid teeth underneath, which increases the nut and workpiece Compared with the combination of ordinary nut and washer, it is stronger and more tensile.
The surface contact area of the flange nut and the connecting piece is large, which determines its use. When the two parts of the bolt and nut are connected for the convenience of connection, the bolt hole of one part is usually processed very large, so that the two parts It is very convenient to align the two holes. The bolt connection can be realized without correcting the two holes. If the bolt hole is enlarged, it will inevitably lead to the reduction of the contact area between the ordinary nut and the connected part. In this way, this flange surface is used. Nuts can avoid this situation.
The flange surface of the nut flange surface has grooves, which not only increase the contact area, but also prevent loosening, which is common in rotating mechanisms.
