U-Bolt Solutions - FAQs

A u-bolt is a type of bolt that is shaped like the letter U with screw threads on both open ends. They are a ubiquitous fastener commonly found on a wide range of vehicles and machinery. They are frequently used to support axles, leaf springs, pipes and more.
U-bolts are a major part of many vehicle suspension and powertrain systems. They are often used to connect a vehicle’s axles to the leaf springs or to the body of the vehicle.
U-bolts should never be reused when repairing or replacing suspension components like leaf springs. U-bolts function as a simple clamp that holds components together, but they are typically torqued to yield. This causes the bolt to deform slightly and become unsuitable for reuse, meaning u-bolts should always be replaced during servicing.
Like most fasters, over tightening a u-bolt can strip the threaded ends, damage the nuts or even shear the body of the bolt. While you are unlikely to damage the leaf springs or axles, damage to the u-bolt may not be apparent until it shears under load. Check the manufacturer’s torque specifications and avoid over tightening.
U-bolts come in a variety of shapes and sizes, depending on the application. They are typically classified by a rounded, square or semi-rounded profile. U-bolts are also available in a variety of sizes, diameters, coated finishes, thread pitches and more.
