Attention Problems in Installation of High Strength Hexagonal Bolts
In the installation of high strength hexagonal bolt, we need to pay attention to the following matters to ensure the quality of high strength (including internal and external) hexagonal bolts.
1. Installation and construction of high-strength hexagonal bolt should be avoided in rainy and snowy weather to avoid affecting construction quality.
2. High-strength hexagonal bolt is connected to the warehouse on the day they should be used. The unused high-strength bolts on that day can not be piled up in the open air. They should be returned to the warehouse as many as possible so that they can continue to be used the next day.
3. High strength hexagonal bolt in the installation process, if need to expand holes, must pay attention to prevent metal debris clamped between the friction surface, must be cleaned before installation.
