Common nuts (Figure 2)Flange nuts (figure 1)
The size of the flange nut and the general hex nut is basically the same as the thread size, but compared with the hex nut, it is a one-piece washer and nut, and there is a non-slip tooth pattern below, which increases the nut and the workpiece The surface area of the contact, compared to ordinary nut plus washer combination, more firm and greater pull。 The
The surface contact area between the flange nut and the connector is large, which determines its use. When the two parts of the bolt and nut are connected for the convenience of connection, the bolt holes of one component are usually machined very large. It is very convenient to find the right moment, and the two holes can be connected with bolts without exactness. The bolt holes are enlarged, which will inevitably lead to the reduction of the contact area between the ordinary nut and the connected parts. This kind of flange surface is used. Nuts can avoid this situation.
There is a groove in the flange surface of the flange surface, which not only increases the contact area, but also has the effect of preventing looseness, which is common in rotating mechanisms.
Does the hexagonal flange nut need flat washers and spring washers? The flanged nut surface itself has the function of anti-slip and stoppage of the flat pad and spring washer, so it is not necessary to add flat pad and spring washer when assembling, and this would be counterproductive and worthless!
