U BOLTS- Spring bolt, center bolt For benz truck

U-bolts are fasteners that are in the shape of the letter U, which contain two male threads, one on each end of the bolt on to which a mounting plate bracket and attachment nuts are placed. While most U-bolts feature a semi-circular profile, some have a squared-off shape. These fasteners are typically not fully threaded, as they function to clamp an object in place. They are used in a range of applications from supporting pipe to automotive use on drive shafts and exhaust systems. Some designs include rubber coating to preclude wear from the movement of metal against metal. Other designs of U-bolt add thick rubber gaskets to reduce the effect of vibration and to control noise. Non-metallic designs are also available for use in applications where there is a risk of the U-bolt making contact with an electrically powered conductor.
