How To Use Bolt?

Bolts are an important fastener and are widely used. Some people may want to know how to use bolts. As a professional fastener manufacturer, Xinchi Fastener Company has many years of experience in the fastener industry. We are happy to introduce fastener-related knowledge, such as the fastening method and the fastening principle of bolts.

Before connecting the bolt, it is necessary to confirm that the bolt and nut pitch, tooth type, rotation, and other parameters are consistent.

Before fastening, it is necessary to thoroughly clean the sludge, carbon deposit, coolant or oil, and other debris and liquid in the bolt hole and check whether the thread is in good condition and whether the bolt is elongated.

When tightening the bolt, it is necessary to tighten it according to the torque specified in the instruction manual. If there is no provision, it is necessary to reasonably determine the tightening torque according to the diameter of the bolt.

When removing the cylinder head bolt, the engine must be completely cooled before it is carried out. At the time of disassembly, it is necessary to be in accordance with the “from both sides to the middle diagonal uniform release” principle, in order to prevent the cylinder head from warping deformation.

When the same part is fastened with multiple bolts, it should be tightened step by step in a certain sequence according to the shape of the connected part and the distribution of the bolts (generally divided into 2~3 tightening times). If there are dowel pins, tighten them from the bolts near the dowel pins.

When tightening the square or round arrangement of group nuts, it must be symmetrical.

When tightening the rectangle-arranged group nuts, it should start from the middle and expand symmetrically to both sides gradually.
