In automotive, center bolts are essential components of leaf spring assembly. In a leaf spring assembly, the center of each leaf is a hole. The bolt gets slotted through this hole in each of the four, five or more leaves that comprise a spring. Effectively, the center bolt holds the leaves together and maintains its connection with the axle. The center bolt head contacts the axle which gives the truck its rear suspension in combination with the leaf springs.

Indeed, center bolts are important elements of leaf spring assembly. Despite its importance, the center bolt is also one of the most vulnerable parts of a leaf spring. Due to this fact, to ensure the center bolt does not break due to the flexing of leaves, U-bolts are required to bind leaf springs tightly together. On each side of the center bolt, U-bolts clamp the leaves into a tight spring. Also, it is imperative to buy bolts only from trusted bolts and nuts suppliers in the Philippines. There are plenty of hardware stores out there that sell what looks like quality material on the outside, but inside the built is poor.
