Is there a reason why the flange bolts are mounted with the bolt heads in one direction?

Flange bolts mount the bolt heads in one direction for the following reasons:

1. Unified appearance: When the flange bolt heads all face the same direction, the overall appearance is more neat and beautiful, which meets the requirements of the specification.

2. Convenient operation: If the direction of all bolt heads is consistent, it is more convenient to use tools such as wrench or wrench socket for tightening installation or disassembly.

3. Convenient inspection and maintenance: For equipment and structures that require regular inspection or maintenance, such as pipes, containers, etc., if the flange bolts heads are in the same direction, it is easier to check the bolt state, tightness and sealing performance.
