It is necessary to have enough space to operate the screwdriver and other tools to tighten the screw. In some narrow and compact environments, such as small buried transformer boxes and control cabinets, the operation may be limited, it is difficult to ensure that the screw can be tightened correctly, and it is easy to cause the screw to loosen or fall off, which increases the construction difficulty and installation risk.
