Among the important uses of bolts and nuts, the following can be mentioned. The use of bolts and nuts in the construction industry includes bolted and bolted metal structures and bolted and bolted metal structures, spatial structures and light structures. The most widely used bolts and nuts in the metal frame include steel bolts and nuts grade 8.8 and 10.9 with the standard DIN 931 - DIN 933 - DIN 934 and HV bolts and nuts in the standard DIN **** - DIN **** and steel washers in the standard DIN **** . Today, these types of bolts and nuts are widely used in the industry.
What is a nut?
A nut is a ring-shaped, round or polygonal body that is threaded into its hole. Nuts are auxiliary fittings for screws so that the screws are closed more tightly in their twisting path. The nut and the screw are locked together in the female and male positions. The thread and groove of the nuts with the thread and groove of the screws must have a special fit for the correct rotation of the screw inside the nut. Nuts are usually made of steel, iron or other metals, but plastic nuts are also made for plastic screws.
What is a washer?
The washer, in fact, is an intermediary between the nut and the body and is a ring made of metal or sometimes rubber. Washers are usually used to distribute the load of bolts and nuts. There are various reasons for using washers; For example: 1. It is placed under the nut so that the rotation of the nut does not damage the main part. 2. Prevents nut or screw from loosening due to vibration. 3. It transfers the pressure resulting from tightening the nut on the work piece better.
