When using bolts or u-bolts with a slotted hole, what is the correct installation order for the components?

The correct order for installing bolts or u-bolts with a slotted hole is to place the flat washer first, followed by the lock washer, and then the nut. This sequence is essential for ensuring a secure and stable connection.

The flat washer serves to distribute the load of the nut over a larger area, which helps prevent damage to the material being fastened and reduces the risk of loosening due to vibrations. The lock washer is specifically designed to provide resistance against the nut's tendency to loosen, helping maintain the integrity of the connection over time. By placing the lock washer after the flat washer, it can effectively grip the nut and the bolt shank, enhancing stability.

This installation order promotes proper tensioning and alignment, which are critical for maintaining structural integrity in telecom tower construction and other applications. Choosing this configuration also adheres to best practices in mechanical fastening, further ensuring safety and efficiency.
