Installation steps of 8.8 hex head bolt
Preparation stage: Select 8.8 grade bolts of appropriate diameter and material, as well as matching nuts and washers. At the same time, prepare installation tools such as wrenches, torque wrenches, etc.
Clean the work area: Make sure the installation area is clean, tidy, and free of debris and oil.
Positioning and installation: Determine the installation position and direction of the bolts according to the design drawings and requirements. Pass the bolts through the components to be connected, and install the nuts and washers.
Tightening: Tighten the bolts with a wrench or torque wrench. When initially tightening, it should reach 60%~80% of the standard axial force of the bolts; when finally tightening, professional tools should be used to set the appropriate tightening torque to ensure that the bolts reach the specified preload.
Precautions for 8.8 hex head bolt
Preload control: The size of the preload is crucial to the stability of the bolt connection. Insufficient preload will cause loosening and deformation, while excessive preload may damage the bolts or connected parts. Therefore, the preload should be strictly controlled during the tightening process.
Anti-loosening measures: To prevent the bolts from loosening during use, anti-loosening measures can be taken, such as using locking washers, applying anti-loosening agents, etc.
Regular inspection and maintenance: For 8.8 grade bolts that are used for a long time, regular inspection and maintenance should be carried out. Check the tightening state, surface defects and corrosion of the bolts, etc. If there are any abnormalities, they should be handled in time.
