Square Head Bolt
A Square Head Bolt is a bolt featuring a four-sided (square) head, providing a larger gripping surface for wrenches and greater resistance to rounding compared to hex bolts. Commonly used in vintage machinery, structural assemblies, and architectural restorations, square head bolts also offer a traditional look and are ideal for applications where a wrench may need to grip from multiple angles.
