Precautions for the use of hot -dip galvanized bolts
1. Product quality: Clean the surface rust, oil pollution, nuts of the thread wall, weld, etc.; after contacting the friction surface treatment, the requirements of the anti -scratch coefficient should be met. The high -intensity thermal heat -soaking galvanized bolts used should be equipped with supporting bolts and cushions, and should be used according to the supporting facilities, and must not be changed; during the installation process, the processing of the processing of the components should not be covered with oil, soil and other debris. ; The friction surface of the component should be kept dry during the installation process and must not be operated in the rain; during the installation process, the friction surface of the component should be kept dry. Before installation, check and correct the deformation of the steel plate connected to the steel plate; during the installation process, the hammer is strictly prohibited to prevent the thread of damage to the nut. When using, please check the electric wrench regularly to ensure the accuracy of the torque and operate in accordance with the correct tightening order.
2. Installation safety technology: 1. The size of the wrench that is opened with a wrench shall be consistent with the nut size, and it is not advisable to use a small wrench plus a pipe. A fixed wrench should be used during high -altitude operations. If you use a activity wrench, you should use a rope to fix it and tie the seat belt. When assembling the connection bolt of the steel component, insert the connection surface or detect the thread holes by hand. When picking up and placing the iron plate, your fingers should be placed on both sides of the iron pad. In the construction of hot -dip galvanized bolts, we must pay attention to the above problems to avoid unnecessary trouble.
