The square head of these bolts typically has four equal sides, forming a square shape. This design allows for a greater contact area with the wrench or socket during installation and removal. The larger contact area provides improved torque transfer, making it easier to apply high levels of torque compared to other bolt head types. They are suitable for use in construction, machinery, infrastructure, and agricultural equipment, among others.
