A socket impact wrench is a tool consisting of multiple sockets with hexagonal or twelve corner holes and equipped with various accessories such as handles and extension rods. Socket impact wrenches are particularly suitable for tightening bolts or nuts with very narrow or deep indentations. Socket wrenches are mainly used in situations where bolt space is limited, and can only be used with socket wrenches. In addition, when the nut end or bolt end is completely lower than the connected surface, and the diameter of the concave hole cannot be used for open end wrenches, adjustable wrenches, and ring wrenches, a socket wrench is also required.
