Definition:
Square nuts are four-sided nuts asopposed to the more common hex(six-sided) nuts.The surface area onthe flats is larger than hex nuts, whichreduces wrench slippage.
Application：
They are commonly used in construction, automotive engineering, and mechanical systems. Square nuts provide more surface area for two parts to connect than a typical nut, increasing the connection’s strength, and making them especially vital in applications requiring heavy-duty fastening.
