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.

Product Comparison and Advantage Section
Set up comparison content to highlight the advantages. "Compared with ordinary hexagon bolts, Mushroom Head Square Neck Bolts have obvious advantages in wood connections. Ordinary hexagon bolts are prone to loosening due to vibration or external forces, while the square neck design of the Mushroom Head Square Neck Bolts effectively solves this problem. In a simulated vibration experiment, the wood structure connected by ordinary hexagon bolts became loose after vibrating for [a certain period of time], while the structure connected by Mushroom Head Square Neck Bolts remained stable."
