Trapezoidal nuts they can be made of bronze or steel. The nut thread is H7 tolerance.
Single-threaded trapezoidal brown nuts are twice as high (l = 2xd) than the diameter of the mating bolt. The material is BA2 grade aluminum bronze.
Trapezoidal steel nuts with single thread (round and hexagonal) are 1,5 times higher (l = 1,5xd) than the diameter of the mating screw. The material is free cutting steel.
The designation "Tr ... x ..." tells about the size of the trapezoidal screw thread.
For nuts, the first number is the diameter and the second number is the length of the nut.
Round nut it is an element without which it is difficult to imagine a machine or production installation operating efficiently. Trapezoidal round nuts are a necessary supplement to trapezoidal screws. It is a component that unites machine parts and affects the stable operation of the entire device. Connected installations, thanks to round nuts, are not only more solid, but also due to the fact that all parts of the devices are properly seated and mounted, round nut it also affects the silencing of the working machine. It is worth remembering that an additional factor, which translates into an increase in the noise of working machines, may be the play between individual elements of the installation.
Round nuts are an element that tightly fixes individual parts of precise mechanisms. It is therefore worth remembering that the durability of the nuts also translates into a longer service life of entire machines. That is why round nut it should be made of durable and resistant material. The nuts that you can find in our assortment are made of C45 carbon steel and A2 stainless steel. The selection of the appropriate raw material translates not only into the strength of the nut, but also into other desired properties. An important factor is, for example, the appropriate roughness of the side surfaces of the thread, which definitely translates into the force with which machine elements are twisted.
The use of round nuts is really wide. Solutions of this type are suitable for fastening various types of industrial structures. It is worth emphasizing, however, that it is steel round nut rather, it is suitable for the restraint of machine components that operate at low to medium speed. In the case of devices characterized by intensive work, there is a risk that the steel elements will rub against each other with considerable force, which in turn may lead to their rapid wear.
