Precautions for
Hexagon Bolt Installation
If you want to connect two separate steel structure components together, there must be a medium in the middle. The bolt is this medium. There are many types of bolts. According to the size of the bearing capacity, they can be divided into ordinary bolts and high-strength bolts, while hexagonal bolts It is one of the most famous bolts.
1. For dynamic load or hexagonal bolts installed in important parts, spring washers should be placed according to the design requirements. Spring washers cannot be placed at will, but should be placed on the side of the nut.
2. When installing high-strength hexagon bolts. The bolt should be able to penetrate into the gap freely and smoothly. If the size and position of the hole are not suitable, do not force it. If you find that the hole diameter is smaller than the bolt diameter, you need to use a power drill to drill the hole larger.
3. According to the connection method, high-strength hexagonal bolts can be roughly divided into three categories, namely friction connection, tension connection and pressure connection. At present, friction connection is used in most occasions.
4. Hexagon bolts have their own installation sequence. During installation, it should be gradually advanced from the part with high rigidity to the unconstrained free end. From the initial screwing, re-tightening to the final screwing, it should be expanded from the middle to the four sides and then tightened one by one according to the sequence. After each screwing, you can put a mark on it, so as to avoid the phenomenon of leak-stop screwing. The bolts on the same part should be installed within one day.
