Product name: Square Nut

Square nut is a four-sided nut. Compared to standard hex nuts, square nuts have a greater surface in contact with the part being fastened, and therefore provide greater resistance to loosening (though also greater resistance to tightening). They are also much less likely to become rounded-off after repeated loosening/tightening cycles. Square nuts are typically mated with square-headed bolts. Square nuts are used along with flat washers in order to avoid damage from its sharp edges and increase the strength of the fastener. Square nuts can have standard, fine or coarse threading with platings of zinc yellow, plain, zinc clear, tin and cadmium, among others. Most can meet either the ASTM A194, ASTM A563, or ASTM F594 standard.

The role of the square nut

The square nut acts the same as the ordinary nut and acts as a fastening. Of course, tightening is only the most basic function of the nut, otherwise the nut will not be divided into many types.

Different types of nuts have different functions and suitable environments are different. The square nut is also the same. The ordinary nut is hexagonal. The angle of rotation when using some wrenches is relatively small. It is very difficult to use the hex nut in some limited space. This uses the square nut. The square nut has a large tightening angle and is easy to install.

Square nut heat treatment details

Square nut heat treatment is one of the most important processes in mechanical manufacturing. Compared with other processing techniques, heat treatment does not change the shape of the workpiece and the overall chemical composition, but changes the chemical composition of the microstructure or surface inside the workpiece. Workpiece imparting and improving certain performance. And its characteristic is to improve the memory quality of the workpiece, which is not visible to the naked eye.

In order to enable metal workpieces to have certain mechanical, physical, and chemical properties, heat treatment techniques are indispensable in addition to materials and various molding processes that are reasonable at the time of selection. In particular, steel is the most commonly used material in the machinery industry. Its microstructure is very complicated. At this time, it can be controlled by heat treatment. Therefore, the most important part of the heat treatment technology of square nut is the heat treatment of steel. In addition, when making nuts, other metals can be mechanically, physically, and chemically modified by heat treatment to obtain different performance properties.
