SQUARE HEAD BOLT 10MM X 25 17*17 A2

A square bolt is a threaded fastener with a four-sided (square) head designed to provide a larger gripping surface for tools and resist slippage during tightening. The square head also prevents the bolt from turning when used with a square hole or when embedded into wood or metal, making it ideal for applications where the bolt must remain stationary as the nut is tightened.
