Certainly! A square head plug and a hex head plug differ primarily in the shape of their heads, which affects the tools required for installation or removal. A square head plug has a square-shaped head, typically requiring a wrench or socket with a matching square opening. In contrast, a hex head plug features a hexagonal head, which is compatible with a standard hex wrench or socket, offering more points of contact and often easier handling in tight spaces.
