Threaded connections are now widely used in the assembly of various machines and mechanisms, as they allow for the secure fixation of individual parts within a complex structure. Another factor in favor of this approach is the relative ease of assembly operations during construction and disassembly during scheduled maintenance or repairs following the failure of individual components. To simplify the tasks of fitters and mechanics as much as possible, a targeted search for the ideal shape of parts and the tools used for their installation and removal was conducted for many years, until all the advantages offered by hexagonal cross-sections were determined in practice. To turn them, simple open-end wrenches or space-saving sets of socket heads of various sizes with a removablewith a collarfor use with multiple instruments simultaneously. To ensure that all assembly and disassembly procedures proceed without significant problems, the parts themselves must be manufactured with a high degree of precision, meeting the tolerances required by standards for various types of tools. This is precisely why there is currently high market demand for these calibrated steel hexagon, which is today the most common material for obtaining blanks in the production of all kinds of components used in the construction of vehicles, as well as the creation of power machines and industrial equipment.
The most important advantages of this type of ferrous rolled metal include:
After the calibration procedure, the degree of conformity with the calculated geometric shape of the cross-section becomes close to ideal, both in terms of the dimensions of individual sides and between them in pairs, and in terms of the straightness of the axis along the entire length of the product. As a result, the blank created from the rod section initially possesses central symmetry, which ensuresequipartitionMasses undergoing rotational motion. This property is crucial for various axles and shafts, as at a high number of revolutions per unit of time, an imbalance would generate significant centrifugal force, and the resulting oscillations would cause discomforting vibrations and create significant destructive forces on bearing assemblies based on rolling or plain bearings.
Calibration also ensures that the tool fits into the jaws or heads of the keys with minimal gaps between the walls, which has a positive effect on the safety of the corner sections of the part, which bear the main loads of shear deformation when twisting in one direction or another.
The steel grade used as the raw material for rolled products completely determines the mechanical properties of the resulting products. By selecting the appropriate combination of characteristics, such as hardness, wear resistance, impact resistance, and so on, it becomes possible to effectively address existing challenges and ensure reliable operation of the entire structure over a long period of time.
If inherentcalibratedIf the properties of a steel hexagon are not sufficient to meet existing needs, it is worth resorting to replacing it with more expensive analogues.
Analogues of calibrated steel hexagon for solving specific problems
For the chemical and food industries, as well as many types of laboratory equipment, resistance to various chemically active substances is a crucial quality. For this reason, when manufacturing equipment for these industries, aluminum, which is more than twice as expensive, is often used stainless steel hexagon, which can withstand contact with acids, alkalis, strong salt solutions and organic molecules.
Brass hexagon
In electrical engineering, the most important characteristic of any material is its ability to conduct electric current. To minimize energy loss or eliminate unwanted heating of individual components of equipment, many components are made using brass hexagon This copper alloy also boasts high antifriction properties, which is why this type of non-ferrous rolled metal is often used to manufacture components of plumbing fittings subject to intense friction or components used in engineering that function as friction bearings.
