Mushroom head square neck bolts, also known as carriage bolts or coach bolts, feature a distinctive mushroom-like head with a square neck. These one-piece forged fasteners are commonly used in wooden structures, where they provide secure anchoring. The squared section beneath the head prevents rotation, making them ideal for applications like timber construction and iron strengthening plates.
