1. The definition of 904L U bolt

A U-bolt is a bolt in the shape of the letter U with screw threads on both ends. U-bolts have primarily been used to support pipework, pipes through which fluids and gasses pass. As such, U-bolts were measured using pipe-work engineering speak. A U-bolt would be described by the size of pipe it was supporting.

 

If the U-bolts have been holding the spring so tightly to the pad that no movement occurs, there can be little wear. The U-bolt top plate is important for two reasons: It maintains the U-bolts directly in the line of pull and proper alignment with each other.

 

2. How to Install  904L U-Bolt

If the U-bolts have been holding the spring so tightly to the pad that no movement occurs, there can be little wear. The U-bolt top plate is important for two reasons: It maintains the U-bolts directly in the line of pull and proper alignment with each other.

Step 1

Place the U-bolt around the pole or pipe. The threads should point toward the object being fastened.

Step 2

Slide the U-bolt clamp over the part you are attaching. Push the two U-bolt threaded ends into the two holes on the U-bolt clamp.

Step 3

Place a washer on each of the threaded U-bolt ends. Place a bolt on each threaded end.

Step 4

Turn the first bolt by hand in a clockwise direction until snug. Repeat this with the second bolt.

Step 5

Tighten the bolts with the wrench. Follow the manufacturer's recommendation pertaining to the amount of torque required.
