When installing high-strength (including internal and external) hexagonal bolts, you need to pay attention to the following matters to ensure the quality of high-strength (including internal and external) hexagonal bolts.
1. The installation and construction of high-strength (including internal and external) hexagon bolts should be avoided in rain and snow, so as not to affect the construction quality.
2. High-strength (including internal and external) hexagonal bolts should be taken out from the warehouse on the day of use. It is best to use as much as possible. The high-strength bolts that are not used up on the day cannot be stacked in the open air. They should be returned to the warehouse as many as possible. Continue to use the next day.
3. If high-strength (including internal and external) hexagonal bolts need to be reamed during installation, attention must be paid to prevent metal chips from being caught between the friction surfaces, and they must be cleaned before installation.
