U-Bolt, 3/4 in Diameter, Flat-Top
SAF-Holland

The U-Bolt is a critical fastener in leaf-spring and axle assemblies, delivering secure clamping force to hold springs, hangers, and axle components in proper alignment. The 3/4-inch diameter, flat-top configuration provides a stable seating surface that resists deformation under heavy preload and high-torque conditions typical of commercial trucks. This part is manufactured from medium- to high-strength steel with protective finishes to resist corrosion in challenging environments, including exposure to road salt and humidity. Correct U-bolt selection affects axle alignment, ride quality, and brake performance by maintaining consistent spring seating and minimizing axle shift during cornering and braking. When installing, follow torque specifications from the vehicle manufacturer and ensure proper washout clearance to prevent thread binding during maintenance. This part is designed for dependable long-term service, with replacement cycles driven by wear, corrosion, and U-bolt fatigue life.
