Correct Torque Calculation

Calculation of tightening torque to preload a bolt is an important thing to check the force. All the formulas to check the correct calculation regarding nuts and bolts are mentioned in a popular book which is named as Machinery’s Handbook. So read forward to know some of the basic things which you need to take care for the tightening torque calculation for bolts.

Standards are important: This process is an important thing when it comes to torque and it should be done keeping in mind the standards set by the international authority of different countries around the world. As far as unified inches screw threads are concerned the only valid and accepted range which deals with the size of these bolts is ¼ inches to 1 ½ inches. This figure should not be changed because it is based on the standards which are set by UNC, UNEF and UNF.

Materials used for construction: The material database which is used for different sized screws and steel bolts is also generally mentioned in the calculator. In cases of such situations where the user or client wishes to get defined properties related to strength for a bolt, then you do not need to calculate the database. Therefore, no need for the calculator because the properties mentioned by the user are the ones which will be used. Generally, the database is prepared for the use of different properties of steel bolts which are mentioned in a book namely machinery’s handbook. This book is considered to be perfect for such measurements of all the correct sizes which should be used.

Different grades database: Different types of material databases are there but generally ASTM and SAE Steels with different grades are used for such purposes of making bolts and screws made up of steel. These different grades are also used according to the standards mentioned in books and given by the authorities.

Calculating different categories: There are different properties which are needed to be taken care of while creating different bolts. There is bolt tightening torque which is required to be calculated so that the dimensions are perfect and there is not a difference of even of a single inch to maintain perfection. There is a minimum length which is to be maintained to keep all the threads engaged with each other so that they are not fallen apart from each other. Another important thing which is to be kept in mind is that the dimensional properties of bolt and nuts are kept in an exact manner or otherwise they won’t fit and will become totally useless.

The special dimensions shear area of thread area on internal as well as the external area of all bolts and nuts. The basic things can actually change a lot in the actual dimension which will make these little accessories become useless despite all the efforts put on them so they should be taken extra care of. All these formulas are being clearly mentioned in the section of “list of the equation”.
